Game is excellent but I fucking suck at it so badly that I can't pass level 1 . jfc i'm so retarded lmfao . joke aside though , It's basically minesweepr with smut. I especially like that there's a standing model next to the game, makes it fun and hot and pretty dynamic. It's what you'd expect from minesweeper but they add powerups and lose sequence . I'm too dyslexic to tell you more since I coudn't reach level 2. sorry guys . It's fun though . do do try it .

Genuinely everything I want out of my porn games. Really fun. Biggest unique trait that I appreciated is the balance between making status effects feel unique and impairing, but still fun. Also, I already like minesweeper, so there's that.

Eh, not really feeling this one. Normally I like the lewd status effect games, but this one... none of them really seem to effect gameplay much, except for two which effect gameplay WAY TOO MUCH. Parasite status spawns annoying enemies every five turns, and Hypnotism fucks with your UI. Neither of these are sexy, they're just really annoying. It doesn't help that basically everything that adds a status effect adds the full 3 stacks, so you never get any sense of build-up. Also, the game has no real story/plot, and no pay-off in the true ending. You slog through all nine levels, unlock all of the stars, get all of your skills and achivements for the bonus stats, then hit NG+ and it takes it all away from you, loads you down with a boring (but really powerful) self-heal skill and just has you run like 20 levels back-to-back with none of the advantages you just spent the whole game building up to. Then in the end the only story-beat at the end is "Dorothy gave up and stayed inside" (with no sex scene) or "Dorothy finally escaped" with no satisfying conclusion of why you were abandoned down there to begin with, or what was even going on in the first place. It's just a big anti-climax.

I really like this game. The art is good, the gameplay is fun and you can spend a while getting all the achievements. The UI is neat, with auto-updating number markers when you open a tile/kill and enemy. The limit on items you can hold during stage transition is cool, makes you think about what you want to bring (I mostly held damage stuff and was fine) I do think there are areas for improvement, the ingame xp system feels pointless (leveling at random times for a choice of three random items, which might be currently useless), some items have the wrong description (says has upgrade cap of 9 but can't upgrade) and the upgrade system feels a bit odd. As in several items have upgraded forms but you just have to find them instead of upgrading them directly, or how items can either be upgraded once or nine times which feels arbitrary. The turn limit/timer also never truely like a threat, even in the new game plus aiming for the perfect ending. It raises your EP but having max ep isn't that bad, and with items you can reset it before moving on. Over all I like this game

As a game that improves on the basic concept that is mine sweeper, this is a great game But as a h-game, it lets much to desire. The art is good but the scenes arent THAT good to justify going through the game that many times Still would recommend it since you can play until you get bored and then push the "Unlock Everything" button in the menu

I thought this game was pretty good. I really like the theme and the content included in this game are honestly pretty fleshed out (pun intended) and are pretty fun. I like the amount of different statuses you can have and how the picture of the protagonist updates to show them together. The item system is also honestly pretty fun and you can become almost unkillable if you combine them correctly. My problem is I think there are a few mechanics/quirks to this game, gameplay wise that are just annoying and not really fun. For example the parasite status will spawn an enemy every 5 turns which gets old quick. The hypnotized status doesn't actually really affect outcomes at all it just makes it take longer to read items or enemies. Additionally the two "endings" you get from playing new game plus are extremely underwhelming (exact same CG, just different text), and I wasn't even able to get it legitimately. The "new game+" level is at least 150 levels long but sometimes the game will glitch and not spawn you enough keycards to open every chest and the exit. Finally, as many other reviewers have said, there is a noticeable lack of content and the game is pretty short, and it is not very replayable, honestly. This seems to be a common trend in many of these types of games though so I don't really have much else to say on that. The way I'd say this game is is that playing for like 3 hours lets you see 90% of the content has to offer and trying to see the last 10% is not worth it and is just boring. Basically, play the game, its good (if short), but don't bother with new game plus at all, that was a huge waste of time for almost no new content. You honestly don't even need to bother getting 3 stars on every level, you wont get any more content besides "skills" to make the game easier.

The gameplay alone is a solid 5/5 that innovates upon minessweeper mechanics however the lack of Story or over arching plot point is really offputting since there is plot but its not explained and its not even the Hidden type of plot, there really is just a lack of story The hentai art is also 5/5 which is great but it also stings harder that the game has too little content aside the minesweeper gameplay and great art Honestly could have been a solid 11/10 if there were more content to the game. Ill be keeping this developer in my radar

never before have i actually enjoyed the "gameplay" of a porn game. almost all of them exist to just waste your time. this one is different though, which is impressive. it's obviously a minesweeper game, but it deviates enough and has a slightly different ruleset to make it a unique and fun challenge. the way that you're limited from revealing a tile not-adjacent(orthogonally) to one already revealed forces you to actually make use of the special items the game gives you access to. if it chose to, without the porn it could stand alone as a decent(not amazing, but decent) minesweeper game. but this does have porn, and on that front the art+kink choices are great too.
ob123 2025-09-24
TLDR Buy on discount. Good game, Not enough porn. Too bad. Gameplay Action Mine sweeper with item and perfect run masochist simulator But also, it's one of the few games that make me forget that the sun is rising. Thumbs up for that. Sex scene Too few to be satisfied. Awfully shame. Tentacle rape Hypnotize sex Machine sex Rape and humiliations Have stomach bulge but no birth scene like a face hugger just slip out of her vagina, and she doesn't bother by it but compare to horrendously long game over outro? It upset me.

I am an absolute sucker for both Minesweeper variants and the Ero-Trap-Dungeon format. This is right up my alley, and I find it to be a good one-of-these. It is also extremely hard to recommend this game to anyone who isn't into both those things. As a warning, the NG+ "level" is an absolute slog and you should probably skip it.

The sex appeal in this game is weirdly restrained, your character can be depicted as growing more and more horny as her outfit grows more risque. However there are very few depictions of out and out sex here, only in the Game Over CGs, and even then they're only one singular image with minute changes to them. Very disappointing, not even closeups of genitals getting railed. The main draw of this game is the gameplay and art as you progress through a facility overrun with alients and infected robots. The fetish of this game is focused on your character getting infected by either alien monsters or infected robots, and its nailed perfectly . There's really well drawn art of your character getting attachments to her body that affect her behaviour that look monstrous enough to resemble alien infestors but look good enough to be morbidly erotic as they infest your character. The combination of the tentacle suit, eye mask, and enlarged breasts is topnotich transformation erotica. The gameplay is basically minsweeper but with monsters that can attack you and you can only click tiles in cardinal directions, it's fun enough, especially with the skill trees you can unlock across the game. For example, I was worried early on when I wanted to intentionally screw up to get monsters to infect me, but since you can only get infected when you click on a tile with a hidden tile, what I wanted would have been based on a dice roll. Luckily, I discovered there was a whole skill tree that let you infested even if you aren't ambushed, with bonuses if you get horny and infected enough. So I had whole runs where my character got ambushed by as many enemies as she could whilst falling through every trap to grow more warped and horny. It was really amusing and very erotic, I was shocked that this game didn't have a corruption tag. It's a short and sweet package, but I have one massive problem , New Game+. This is a mode where you have to complete the whole game in one sitting. Three problems with this: Your skill tree is completely disregarded for a preset, so your playstyle is tossed to the side. Either ending you get doesn't really do much to address the cliffhanger ending in Normal mode. The minesweeper gameplay is not enjoyable enough to sit that long through for one. I recommend just using the unlock button for the rest of the content at that point, there's not much else past the three sections of the facility that take up the main game. The story and erotic payoff is gimped, but the art's good and the gameplay works well. Press the 4th menu button and the furthest right button on the 4th bar for the english translation, and have fun and don't get invested in the CGs or the writing.

Played version 1.08 Good Taking too much damage damages the character’s clothing on screen Receive status effects that alter the character on the UI. “Aroused” changes the character’s facial expression The gallery lets you view defeat illustrations without having to read all the scenario text. Just look at the image and its various stages. Ability to zoom in, move it around the screen. The gallery lets you view the character with all possible permutations. Change facial expression, outfits, tentacles, etc. The gallery is fully unlocked from the start in the menu Internal x-ray view can be seen at all times Good character art Selecting to use a Charged Ammo item causes the character’s gun to glow The character shown in the main menu cycles through different variations when you leave and return to the main menu Achievements to unlock, which grant game bonuses The revealed traps in the grid don’t automatically affect you unless you choose to target them. This means you decide when to lose closing, get tattooed, become aroused, etc. There’s a button in the menu to unlock all the gallery, all achievements, and complete all levels Issues Game starts Japanese instead of providing a language select. You have to randomly click menu buttons to find the language select. Game starts fullscreen, but low resolution The first level tutorial has screenshots with explanatory text. The explanatory text is translated, but the text in the screenshots isn’t Spelling mistakes Many icons in the UI that don’t have a tooltip when moused over Red down arrow: # unrevealed enemies remaining / total enemies Blue briefcase: # unrevealed items remaining / total items Orange crate: # unrevealed locked crates / total crates When a level starts, a popup shows the mission name and goal. The window doesn’t last on screen long enough to read it. Starting level 1 always brings up the tutorial, even if you’ve seen it before Can’t drag an item on the field on top of an item you’re holding to swap them The Skill Setting is a confusing menu. What do the stars in the top left mean? Does 3/4 mean I’ve spent 3 of 4 skill points? When an effect is triggered like an enemy dying and them causing damage to anything nearby, all those effects happen very fast and it’s hard to keep up with everything that happened Unclear what “upgrade cap” means on items. An “upgrade cap 9” item can’t be upgraded more than once? The tile art for the area 2 levels makes the light which signifies it can be clicked very small and hard to see at a glance The Skill menu doesn’t let you mouse over and inspect skills that you don’t have access to yet The description for enemies in the gallery runs out of space to display text and there’s no way to read it all

I enjoyed this game way more than I thought I would, despite never having played minesweeper before. The game-mechanics are engaging, and the art is good! If nothing else, at least I've learned the basics of minesweeper!

This game has alright art, but the real fun is the gameplay. A great combination of minesweeper and an RPG. Honestly kind of almost got a bit of rogue-lite elements to it. Whole concept revolves around playing minesweeper, but the mines are a whole bunch of status effects or enemies. Plus you can upgrade your character to make things easier. Even has a NG+.

Game is average, hence 3 out 5. The art at first glance looks good, but then you realize it's the only thing you'll get. There's no animations, there's barely any variation, and the "story" is non-existent and poorly translated. This makes it a pretty hard fap and playing the game doesn't really elevate the experience. You might as well just fap to the images in the previews. The gameplay idea is intriguing. Getting to attack the mines in minesweeper is kind of novel. Unfortunately, it's not really better than a dungeon crawler or a card game at the end of the day. This game has potential but just misses the mark. If there was more gradual progression of corruption or a sense of danger it'd be better. But really, it's minesweeper, and the game isn't really punishing, so it's easy to breeze through the game and never really take too much damage, outside of mimic chests. I love the dungeon crawler style games like Maiden Snow Eve where you walk around with cum dripping down your thigh, worried you might stumble into a boss room where they will gang rape you. The atmosphere, the tension, and the sense of impending doom really make these games. It seemed like this game might have that, but unfortunately it doesn't at all. Skippable game, unless you really dig the character design or play minesweeper for fun in your spare time, then it might bump to 4/5.

If fractions were allowed I'd knock off a half point for a couple typos in item descriptions, but overall great game. There's no animations, and not a lot of what would really be considered sex scenes, but the art is great and there's a wide variety of lewd things that can be done to your heroine as she goes through what is, essentially, minesweeper story mode. If you're one of the people who has spent entirely too much time on minesweeper, this is that but with rpg mechanics and porn. Which I have, admittedly, seen once before but this is imho a more fun and sexier implementation of the concept.
Sonsuka 2024-11-18
I'm be deadass I had more fun with the minesweeper with items. You can miss me with the hypnosis effect. NG+ is kinda hell not worth it. But the gameplay and effects are solid. Couple Hour game in my personal opinion.
Smudgey 2024-11-10
I'll sum it up quick. If you like minesweeper you might enjoy this. The art is great but there is very little of it at all. I'd genuinely suggest just hitting the unlock gallery button in the options menu and save yourself the trouble. And for the love of god don't waste your time with newgame+, all you do is repeat every level in 1 sitting with no upgrades. It's the most boring way to do this sort of challenge; it takes ages and you basically become unkillable with the right items anyway so it just becomes a tedious slog.
