v0.6
New Items Added
Because the warehouse looked too empty! Version 0.6 has added some new items! In addition to the basic four items that are activated by pressing a button, three automatically triggered items have been added! These items will trigger on their own under certain conditions based on probability~
(Actually, the font in the warehouse has been adjusted as well)
【Anti-Magic Shield】
Anti-Magic Shield: Automatically triggers with a 2/3 chance when touching tentacles, infectors, or lust toxin nematodes, repelling the demonic creatures touched. Does it look familiar? Yes~❤ This is actually...
turned into an item!
When you first saw this 【Feminization Device Icon】, it might have been unclear what it meant. It triggers with a certain probability when touching roadside tentacles. This was because when initially conceiving the 【Tentacle-infested Red Zone】, I realized that if we really placed so many tentacles in the scene, players would be entangled by tentacles every few steps! That would greatly diminish the experience. Thus, a mechanism was set up where 【if you touch a tentacle, there's a 1/3 chance of being entangled by the tentacle, and a 2/3 chance that the feminization device icon pops up】, allowing the scene to be filled with tentacles while still letting players pass through~ This is actually a port that will be transformed into an item in a future update~
【Electric Shock Patch】
Electric Shock Patch: Automatically triggers when touching tentacles, infectors, or lust toxin nematodes (prioritizes activation over the Anti-Magic Shield), repelling the demonic creatures touched. Each time the player arrives at a new scene, the shop refreshes items~ Wanting to increase the chances for players to get items that 【prevent entanglement by tentacles】, another functionally similar item was added~ However, the Electric Shock Patch triggers 100% of the time~ Be careful if you want to see the CG of being entangled by tentacles~❤
【Lust Toxin Suppressant】
Lust Toxin Suppressant: Automatically triggers when lust level is full (does not trigger when wearing a feminization latex suit), forcing the lust level to reset to zero.
When players navigate through the Red Zone, they might often have to stop due to a full lust level~❤ If you have the Lust Toxin Suppressant, there's a 100% chance that the lust level will be forced back to zero~ Be cautious if you want to see the masturbation CG~❤
Demonic Transformation
After players complete the game, the hidden characters they unlock are two female demons: Maris and the Succubus. Compared to other characters, these two female demons possess the ability to transform into their demonic forms. The biggest advantage of demonic transformation is rapid health regeneration, along with a certain chance of having vampiric abilities (according to the setting, demons have the ability to regenerate automatically, and can self-repair severed limbs via tentacles). Maris's basic attack involves throwing lust toxin bombs at long range (similar to the attack of a typical female demon mini-boss), but after transforming into her demonic form, Maris switches to melee combat, sprouting whip-like tentacles from her arms for attacks, which include vampiric abilities~
The Succubus, already equipped with a vampiric sword, inherently possesses melee vampiric abilities. However, after transformation, her vampiric abilities disappear, and her melee attack shifts to long-range (similar to Maris's throwing of lust toxin bombs), and as a charge-up type character, she can now charge up both melee and long-range attacks.
Added a 1-second cooldown to Felicia and Maris's charged attacks, similar to melee
Previously, there was a bug where if players used Felicia and Maris to lay mines and then quickly attacked with the left mouse button, they would enter a "rapid attack state." It seems the cooldown system used for laying mines, similar to an item slot, did not affect the melee cooldown system. Laila seems not to be affected by this, possibly because she only needs to charge for more than 0.2 seconds to lay paralysis traps, while Felicia and Maris require about 1 second of charging? In any case, now these characters also have a 1-second cooldown after laying mines, which should have resolved this bug…
Players Can Pass Through Teammates
This might have been overlooked previously.
Felicia's Charge Skill Description Update
After version 0.4, Felicia's charge skills were modified... but the descriptions on the store page and the character selection screen were not updated. These have also been updated in version 0.6!
Bunny Girl/Heavy Handgun UI Update
Previously, I didn't realize that the heavy handgun button was slightly larger, but this has also been updated in version 0.6!
In-Game Mouse Change
When you start the PC version of the game, you should notice that the mouse cursor has changed!
v0.5
Players can pass through NPCs but not enemies
In version 0.4, due to the restriction on melee perspective, we set it so that players could not pass through enemies! However, the inability to also pass through NPCs brought significant trouble. After some time and effort, we finally managed to differentiate between 【Enemy】 and 【NPC】! To be precise, although both use the same body, they will set whether to display a collision body to block the player based on their identity. When detected as an Enemy, a collision body will be displayed to block the player. When detected as an NPC, the collision body will be hidden, allowing players to pass through.
In the White Zone, players can pass through undetected demonic creatures lurking about. Once detected and engaged in combat by a player, they cannot be passed through!
Ongoing Prestige Consumption Companion System
In previous updates, many players reported that prestige didn't serve much purpose and was excessively redundant. Although players need to spend 1000 prestige to rehire a companion after they disappear, the rate of acquiring prestige far exceeds its consumption. To address this, we specially designed another prestige consumption method: the Companion System.
In the Companion System, players can choose one out of five companions to accompany them, consuming 500 prestige every time they enter a new scene, until the prestige falls below 500 and the contract automatically terminates. This prestige system brings three benefits:
It provides players with more options for ongoing prestige consumption.
In a sense, players have the ability to "transport" and "protect" companions on the map. As long as the companionship continues, the companion will not disappear. After the contract is terminated, the companion will decide whether to stay or move to another area when the player leaves that area.
It gives players significant support firepower in the scenes (especially in boss battles, where previously players had to face the boss alone).
The Companion System is displayed when you click on the "Battle Princess Association."
Bunny Girl's Option to Exchange Prestige for Money
In addition to the "Companion" and "Companion System," this update has added an option for "Bunny Girl" to exchange prestige for money (the opposite operation to the journalist who exchanges money for prestige). However, 1000 prestige can only be exchanged for 300 coins. Players can exchange unwanted prestige for money in one go (although it's not particularly economical).
Demon Realm Expedition Mode (Survival-type Gameplay)
Originally, the plan was to unlock additional maps after clearing the game, but due to a lack of time to create new scenes, we temporarily assembled the appearance of the demon realm using models of ruins and tentacles.
The entrance to Demon Realm Expedition mode can be accessed by clicking on government information.
The entrance is designed like a portal to the demon realm. Upon entering, players arrive at a non-randomly generated scene where monsters continuously spawn.
There is also a special rule: any damage taken by the player is considered an immediate failure, and the scene resets immediately upon death (CG is omitted). This mode tests players' ability to avoid accidental damage, with points awarded for enemies killed before dying.
Points feel like (highest record), and the highest scores may unlock different equipment or characters in the future.
Earn points by defeating enemies (Easy ×1, Normal ×2, Hard ×4)
Differently, if players wish to leave the Demon Realm Expedition mode, they must return to the scene's exit and click to exit, otherwise, they will continue indefinitely in
this scene.
PC Version Control Adjustments
Sudden Kneeling
Previously on the PC version, entering shooting mode, holding down the shoot button to charge, and simultaneously returning to movement mode could cause a sudden kneeling bug!
The more buttons a player can operate, the more likely various bugs can occur. On mobile, your right thumb can't hold both the switch and attack buttons at the same time, but on PC, you can press the left and right mouse buttons together, which is why this bug went unnoticed for so long!
Mouse Disappears After PC Version
Smartphone Tutorial This actually overlapped with the forced disappearance of the mouse after the tutorial popped up and the forced appearance of the mouse when opening the smartphone. Now, triggering the PC version smartphone tutorial 1 second after completing the mission has essentially solved this problem!
Mouse Disappears After Death on PC Version
This might have been fine right after the PC version was completed, but updating something else later caused the bug to reappear (although it's unclear why, delaying the mouse appearance by 0.2 seconds seemed to fix the issue~).
Stage and Character Adjustments
Tower Remains on Map After Death
A player reported that after defeating the tower, it still remained on the map, and reappeared when re-entering the scene. This was because the tower was set to disappear 3 seconds after death (initially to avoid overlapping with a bug that spawned small monsters). Now, it immediately disappears from the map and is reported as defeated the moment it is beaten.
Maris's Succubus Form
In the previous Ver.0.4, Maris was used to test the creation of a female front kick attack, but in Ver.0.5, it has been reverted to a flying succubus state.
Adjustment of Bunny Girl's Back Collar Position
During tests of the Bunny Girl, the issue was not noticed with long-haired characters. Now, the combination of the Bunny Girl outfit with short-haired characters has revealed the problem, which has been corrected in Ver.0.5.
Anonymous Text Adds Ending Trigger Condition Hint
It seems most players were unclear on how to trigger the "Nurture the Enemy at One's Own Peril" ending. This update adds a reminder in the anonymous text that states [before reaching District 27 in the Green Zone].
Adjustment of Box Size in Yellow Zone Assault Mission
Players had reported that the collision body of boxes in the Yellow Zone assault mission was too small (actually, it was the same size as the portals). This update stacks the boxes vertically, making the collision size more appropriate.
Lighting on CG Appreciation Interface
Previously, players commented that the CG appreciation interface was too dark (actually influenced by morning/evening settings). After this update, the CG appreciation interface is always set to [morning].
The Steam version has also been completely decoded.
v0.4.2
In response to player feedback, we have removed mosaics from all CG animations, enhancing the visual experience.

A new ending, "Town Liberation," has been added. Unlock the "Memory Room" by reaching any ending.

Entering the green area will now directly generate an exit beneath the player.
Increased the probability of ally recruitment messages appearing.
Added a new phase, "Ceasefire Agreement."

This update has fixed the issue, and the confirmation button will no longer appear if no character is selected.
Please update your game to the latest version for a better experience! Thank you for your support!
v0.1
Initial Release
I wanted to like this game, but it does not satisfy any particular desire. The character art is fantastic, but it would be a stretch to say the animations are mediocre. There's very little non-ecchi H-content either, which is sad considering the character customization available. As for the gameplay, it is a very strange sort of 2D characters projected onto 3D fighter/shooter. Go to each sector and fight enemies until you reach an ending which unlocks 1 or 2 characters and the gallery. It is very poorly implemented however, and just ends up being button mashing, not being able to tell what's going on the screen due to the FOV being so small and the character being in the center of the screen rather than offset.
Jank. Short enough that it isn't a complete waste of time. The scenes are hot. Gameplay Fight for control over an area of a demon infested city. Move to the next area. Repeat. A solid base but a lot of jank all around. The controls are strange. There only like 5 actions. Why the need to split those into two modes? The camera is bad. Far too close and moves too fast. Balancing seems all over the place. Either I take no damage and one shot everything or the enemies spawn faster than I can kill them. Some missions are cleared immediately? I guess the friendly NPCs cleared it? There is only like 4 different areas for 30 city zones. Gets repetitive even for the short play time. New characters have to be bought in the shop. That has completely random items. And you change characters by equipping a different head in the clothing menu. H Only defeat scenes. Automatic minus point. The scenes themselves are quite nice. All rape. Some with monster/tentacle thingies. Your mileage may vary. The gallery gets unlocked after reaching any of the endings. Which I got after like an hour.
For being a one man passion project... it's ok, an improvement over prior entries in some ways but somehow in the shadow of the creators original 2d title. Unfortunately the creator seems to have left this in a permanent state of being an unfinished buggy entry since forming a team to create their next entry. I've logged more time in this game than AC Shadows so I can't rate it any lower.
I'm a bit conflicted on this one. It's at the same time incredible and terrible. The good: CG animations. Holy cannoli, good lord are they hot. If you are in a trap and tentacles/rape mood, this game delivers. It has some weird mix of 3d with 2d added in with some jank that makes it look both hilarious and incredible. Pair that with the voice lines and you have something that will keep you entertained. If you miss any, the game unlocks all of them for you once you get one of the endings. The bad: the learning curve and camera. The game is short, 2h give or take per ending (3 endings total, but only change is a story scene), which ends up making the 30 min you'll waste trying to get accustomed to the controls seem like wasted effort. It's not hard or anything, but the control scheme is off and it has it's fair share of jank on top. The camera sucks. No two ways around it. It's just too close and too centered on the player. You also can't look up or down. I couldn't stand it and had to resort to modding the game to set the camera to a more comfortable position. I probably wouldn't have wasted the effort (and just stomach it) if I knew the game was 2h long. It's bad, but not bad enough to put in the effort to save on 2h of mild discomfort. The mediocre: mostly the gameplay. You just go around completing missions depending on a given area color then go to another adjacent area with the same or different color until you get an ending. Some of the objective types are way too easy, particularly the one to free girls. Also, for a what's similar to a dungeon crawler game, it has virtually no area variation or upgrades. You'll deal the same damage from start to finish, will take the same damage from start to finish, defeat the same enemies in every area, find the same traps, the same objectives... it's too short to become a problem, but it gets old fast enough that I wouldn't stomach unlocking every ending. Bugs: some. There's at least two softlocks. One that prevents you from getting scenes by disabling your character taking damage and one that prevents you from finishing objectives by preventing enemy death.
The animations are really lame 2d paper doll stuff. This game is honestly a waste of time. Right from the start, you take no damage from any of the monsters. The controls are awkward and this game is just a big waste of time. There's much better games to spend your time playing.
the animations are way too janky, the game is frankly terrible and way too easy, overtly clunky controls, quite devoid of content, and somewhat grindy. even if you like femboys, you can find so much better in this site
Feminization Device [v0.3] Not a fan of trap / futa content, but really adore bondage and everything related to it, so I decided to give it a try and overall not a bad... But the game is very mobile type, it works, but most of the time you don't fucking understand what's happening on the screen and gameplay + Lewd scenes - They're not bad + - Map Capture - On the one hand it may seem interesting in the first playthrough, but in the end all you will realize is that you do not understand how map capture works, because after a certain capture the game can simply end on one of the endings In conclusion, I like this author's ideas, but the technical execution at the level of a mobile game just doesn't allow me to treat the game differently
Not Recommended – 2/10 Summary Length: 1-2 Hours Experience: Dungeon Crawler-ish? Bad Story: 1.5/5 Gameplay: 2/5 Originality: 1/5 Scenes: 2/5 Amount of Content: 1.5/5 Characters: 3/5 Performance & TL:2/5 <3
Game is not bad yet its not good either, just played it to kill some time and did that just fine, theres 3 endings out of wich i obtained 2 upon completing the game u get the full gallery, the scenes arent bad but they lack variety as they are mostly tentacle focused. The Gameplay is really repetitive every level you gotta complete your task to liberate the level, boss fights are basically just spam attack and dodge but i think that was due to the build i used u can farm for other costumes wich give all sorts of attacking types and atributes. Lastly at the moment of this rewiew version 0.6 is out and its better than 0.3. Fun little game to add to the completed collection 6/10
I remember playing a game previously made by this developer and that game actually gave me motion sickness, a feeling i havent known i could get by playing video games. So compared to the last iteration, it has made leaps and bounds in all aspects of this game. Yet it still is a flawed game with an interesting style and gameplay. I really wish i could give it a higher rating for its playability, yet its still too simplistic and repetitive to praise. I will say that the sexual scenes are really good and i quite enjoyed the art style, which some people might disagree with. One last thing to mention is the length of the game. Or more precisely lack thereof. The game could be beat in two hours, less if you dont stop to smell the flowers. I dont know if i can recommend this game or not, check your vibes to find out.
very good game, animations are top notch and the ideas behind them are very hot. only thing that will improve this game is adding even more enemies that you can lose to. maybe voice acting for the cutscenes, but honestly not rly necessary since this game likes to keep it simple. 10/10 overall, honestly surprised me because i had WAY lower expectations of this game
[v1.0] I finished it in an hour or two... And I am not sure if it is good or bad. -Story, Originality Corruption forces are taking over the city! Go stop them SuperFemboyCharacter(c). -Renders Interesting 2d models/art. -Sound Some basic sounds and h-sounds. -Playability Hit enemies on a location, or hit objects, or both... Meh... -Performance Runs ok. -Bugs Levels regularly restart due to events. -Animations 2d animations. -Voice Acting Some voice lines. -Grammar Didn't see any mistakes. -Amount of content I cleared up many reagions. Fighting felt junky. And then I got 3 events in a row and the game restarted... I didn't understand anything. I had ~10 more regions to clear and the game finished... Well... Kinda boring?.. Stupid?.. Sudden? The gallery had around 20-30 scenes that mostly consist of tentacles... I am not really a fan, so it saddened me a little. Overall, it is an ok game to go through once, but there is nothing overly interesting.
Designs are hot and the gameplay is somewhat interesting, but: The objective of the game is super repetitive. I cleared the map Left to Right and when I was about to "Win" a left zone turned red for some reason. You have to go through each sector 1 by 1 to get to the other side of the map. By the time I got there, there were several red sectors and the right side of the map was one of them. All while enemies stopped doing damage to me 4 sectors in. Actually tried to lose and I couldn't. This'll still get three stars out of me because I did drop 2 hours on this. It was alittle fun, but couldn't beat it. Katana Bunny OP EDIT: Came back and finished. Turns out you just need to beat 4 bosses for one of the endings (Other being clear map). Also finally had some lose scenes. Oh my<3
version 1.0 on one hand this could be a decent game. like easily 4/5. or even 5/5 with some small changes despite some very weird animations... but i dont think anything about this game is enjoyable in its current state. idk why dev insists on doing controls like this, but game is full of bugs. why would anyone hand out a product like this in this state as "completed" i have no idea. nearly nothing makes sense in this game. it attempts a storytelling about this 3 crossdressing boys constantly injected by estroget to counteract the zombie virus, and i kinda like everything about the premise, or at least i find nothing particularly wrong with it, but then before every story fight there is a cutscene of how the 3 girls now fight against the boss, and then you are dropped into a random area as a solo girl where you clear away enemies and find the boss and kill it and etc... completely unrelated to the storytelling. then H-scenes, there are traps which if grabbed gives an okay sex scene (sometimes hilariously weird cuz animation is too fast and ragdolling the heroine too much) but it's very easy to get away just tap e a couple of times. i dont know how enemies grab you, sometimes they grab you for sex scenes but again it's easy to get away, but at some point i put away my weapon and let every enemy hit me, and my hp still couldn't decrease from full... idk why, i seem to have been invulnerable, maybe another bug, i was with the blue haired heroine. another gameplay problem: blue haired girl/guy is the melee specialist. if enemy hits you and right after you hit them back then that's a critical hit restoring you to FULL HP AND FULL STAMINA... so basically, the more enemy hits you the more easy to randomly get crit hits by spamming left click, so you never die and constantly crit and kill everything. aside from the fact that you don't die regardless because my hp didn't decrease (maybe i overhealed from too many crits? i dont know) but if you are not attacking, you automatically defend if you have stamina as the blue girl... so that deflects dmg as well... and if you attack you crit... so you cant really die. you have to put away your weapon to be able to get hit normally but at that point i was invulnerable. so gameplay is a complete mess, only traps do sexual things to you. but aside from that, story gameplay: you just move around the city, which is distributed to like 20 areas, and you can go to a nearby area... but you can'T jump areas, so if you want to go to the other side of city, you have to go into the area next to you, find the finish point, then again area next to you, find finish point etc, it's boring and makes no sense, since when you clear an area there is NOTHING to do there, why can't you fast travel, it just needlessly wastes your time. i probably forgot many other bugs and problems with the game but imo it's enough. gameplay is absolute dumpster fire. sex scenes although sometimes funny, they are sometimes kinda weird. it could be good but ruined by easy escapes, then invulnerability. so there is nothing going for it. hence i dont recommend this game to anyone. so it's 1/5
Rough game, good-ish porn Polish is missing in critical areas which makes the game a lot worse than it should be. It feels like this is some mass produced genre that I was previously unaware of, the mix of fighting for land and timing-based combat is interesting. There are some tricks to work out which make the game much easier once you do, but they carry some risk still so it doesn't feel like a cheese. Graphics: Quite terrible technically, very basic software with low attention to detail on clipping, animation transitions, animation pacing. The frames themselves are well drawn, but the censoring does ruin it somewhat. Art direction: Dark, red fog in the streets, fighting, people crouching in terror. It presents very effectively relative to how low-budget it seems. Individually there is no part that seems innovative, but the combination is unique and spicy. Music: This kind of atmospheric, haunting sound with little melody is some of the easiest music to write, and you will never remember it. But it adds to the feeling well, so seems like the correct choice. Gameplay: I only tried melee (blue). While attacking you are open to damage, otherwise you always block. I never managed to parry on purpose. Tedious and no dynamic like rolling, but strafing is effective. Environments are closed enough that it is important to keep track of where you go to not get trapped. But FATAL FLAW the traps do no damage and are actually beneficial since enemies disperse while you trap. So the gameplay feels too easy to take advantage of, but I don't mind this in a porn game since it gives a feeling of give and take, control and consent, like BDSM. Story: Seems LLM translated, overly wordy and stupidly boring. Other than the text itself though, the concept is vaguely cool, just not a plot for me.
I have a lot of gripes with this game, but I think I can probably boil it down to three things. The horrific sound effects, bad gameplay, and bugginess The sound effects are borderline ear rape quality. Very low bits per second and very loud. Most sound like monsters screaming into xbox microphones over dial up Gamplay is pretty horrible. There are missions that have infinitely spawning enemies and require ignoring enemies and just running around. The combat is made for a phone Buggy af. I couldn't even play this originally, I had to pass some Unity arguments in order to progress past random black screens and story slideshows
