v1.0.1:
Major:
New Dead Rail Event - Visit the Imps at their home, and finally get a H-Scene for them. Players that have cleared Dead Rail may need to use the 'Replay' function.
Added a 'secret' epilogue scene after beating the main story, beating Pyraxis in the simulation, then going to sleep (People were a little sad that Pyraxis didn't seem to get a resolution, so here we go!)
Minor:
New Cheat: 'One Punch Man' - defeat all enemies in one hit!
Mosquito Girl's First Encounter: Her HP and ATK now scales from 50-60, and 6-8 depending on the day you encounter her. (This was done to help prevent an auto-loss if encountering her on Day 2/3)
Added some extra dialogue to the first bed talk. (I was just experimenting with what deeper dialogue options might look like for fun and decided to slip it in.)
Fixed Daily Mag not fully increasing with Wit, and nerfed the Mag Gain by 50%. (Now 100 Wits = +50% Daily Mag. This should balance out the Esper tree being 50% more expensive than the others.)
Kitsune Support: Now actually works (sorry) - implemented a scaling cap equal to 12 + Monster Rep
Small Mortivira nerf: All sources of damage in this fight deal 1 less damage. Black Candle no longer deals extra damage in phase 2. (Mortivira ended up being the hardest battle and a little RNG dependent, because not only did you have to deal with strong minions, but her spells were just as scary as any of the other superbosses. Hopefully this adjustment will give players more breathing room)
Misc:
Fixed some scenes not resetting Protagonist or Tatsumaki's lust
Fixed Explosive Vial A causing Poison and Bleed to proc twice
Fixed 'Discern' not working in the Azazel fight, causing her clones to pop instantly
Fixed individual doppelganger scenes requiring x2 potions
Fixed Cauldron 3's Tooltip from +1 Wits to +2 Wits.
Fixed Acid Flask A and B not granting an additional Flask.
Fixed HP Regen from Cauldron7a not getting subtracted when selling. In fact, it was actually getting added again when selling!
Fixed a crash when looking at Data Khaos' second tip.
Many many Typo fixes

5 Cute Monster Girls to fight in Turn-Based RPG Combat
Unironically enjoyed the combat the most, decent scenes and lotsa dialogue. Spent some time maxing out all the skills and exploring everything there was to offer. I liked the original characters a ton and the romance with Tatsumaki was well written. Nothing crazy. 6.5/10
Plot: I think it's excellent and lovey-dovey. It's very positive and brings energy into my life. Graphics: I think it's pretty good, judge for yourself. Gameplay: The combat system is very interesting and has various combat styles to choose from. The game difficulty is moderate so its not boring or too discouraging.
This is probably the first time i've played a game from this website and didn't feel like a complete degenerate afterwards. Definitely not my style, but sometimes its good to fap on something where nobody dies or suffers permanent physical or mental trauma in the process... Jokes aside, its a quite good game, art is absolutely mindblowing. The story is alright, but we are here not for the plot (at least i'm not). The gameplay loop is good but i cant say its even necessary, feels more like little something between the main plot and the h-scenes. But overall, i really liked it. Its a Genuinely wholesome and enjoyable experience that i'd recommend to anyone, even if you're not usually into something so... normal i guess.
Huge improvement in overall quality from FwB2. (almost) non-cringey sex scenes (everything still overly amazing/incredible/etc), ai-generated backgrounds are good (except for tree branches), good story and art (dick rarely doubles the size). Much better than third season of original anime, for sure. Sadly, can't find this game on Steam, this is the one I wanna support with $
Holy shit. This game is unbelivably good. To say I did not expect this level of quality from a porn parody is around the same level of understatement as saying "Stalin was a pretty bad guy". The rpg and free-roaming elements are simple and fun, they enhance the experience instead of dragging it down, and the writing is so good, it madeboth Tatsumaki and Fubuki likable and entertaining, while not even the original work could do that. The sex scenes are actually SEXY , and they're spaced right. No pencil sharpening for 40 min and pointless clicking around.
Really good parody game! I love Tatsumaki so much! There are not so many games focused on one character; most of them introduce a big variety of characters and then discard them or forget about them, so a game where you build the relationship with one can be really good too.
Yet another TwistedScarlett game that starts off amazing with incredible art, but the longer it goes on, it's ruined by his obsession with focusing on shit that doesn't matter to his story. He turns every fucking game into either a poorly paced shounen or a philosophical lecture. I'm so fucking sick of playing a game he makes and enjoying it, just for it to drop the ball so hard the longer it goes on, introducing characters I have absolutely no attachment to and expecting me to be so in awe as they blow up cities or throw tanks around (or effortlessly beat characters from OPM in this case, thereby shitting on the source material saying his characters are cooler and stronger). It has the same problems that MG1k did, that FwB1 and 2 have. Stop pretending like you're writing a fanfiction light novel first and write a good porn game. The art is amazing as always, though, so I'll give it two stars.
This is an AI art game that is a parody of One Punch Man (an anime that I have not watched). Despite not watching the anime, I felt like this game is still fun and understandable without having experienced the source material. The premise of the game is that the main character, Hunter, is a fledgling hero but encounters a very powerful monster. The main love interest, Tatsumaki, saves the MC but they both get cursed. The curse is basically that they both can't orgasm to a sexual act twice in a row. From a gameplay standpoint, this means that lot of fetishes are covered despite being one main love interest. This is essentially a monster girl game so other sex scenes involve monsters or transforming Tatsumaki into a monster herself. The gameplay also involves turn based RPG battles. You have 3 main skill trees and it's really cool how you don't have to buy them in order. You have freedom of expression to build your character the way you want. It's also great that the events in the game aren't just random battles. Overall, there's a lot of great writing and character building in the game. It is well made and fun.
Surprisingly a really good game. The art is Ai? Although the tag is missing, which kinda subtracts points. But the other parts of the game make up for the art. Pros: Writing: A good story that very much fits in with the one punch universe from what I know. Tatsumaki has a very sweet relationship that builds throughout the game. H-scenes: Transformations, different positions, very diverse amount of scenes. Each scene having decent writing. Open world: Interactive renpy combat. Not the worst since you can use one punch mode. Monster girls: Tatsumaki is very much the focus on the game, but you can occasionally bang monster girls in the gameplay section. Completed story with information about what the girls are doing after. Cons: Ai art: It's a very good model. The art looks very good...but it still has that ai feel to it. It's hard to describe. It just looks out of place. No harem mention: The game is focused on you and tatsumaki. You can have fun with others, but that's as deep as the relationship goes. Her sister is forgotten. Kinda sad you never see a 3 some scene with them. Fun game
This was a good ride. The game has a surprising amount of content. So points for that. The lewd part is well explained. The art looks good, is ai generated keep that in mind, but it seems they make sure nothing look wierd. There are a lot of fetishes, and there are a lot of scenes with several of the girls, like monster girls not just tatsumaki. Gameplay was also surprisinly fun. There are several trees and for some battles you have to actually think what to do, not just mindlessly spamming. It did not feel repetitive at all. Overall is quite good, my only concern is that it is centered around tatsumaki(not that it is bad). But i would have like to have a bit more content with other girls, monstergirls for example having the affection and all that. And they took the trouble to make odin and genos, yet it is lacking. I understand it would have been a lot of work, but the game is still incredible as it is. If you dont mind the art, then dive in.
good game, funny with good scene. The gameplay is simple but challenging in some parts. Tatsumaki is well written and lovable. The monster girls are reaaally nice and they cover a good variety. Maybe some scene are a bit too similar but is not a big problem per se.
Though the game has a repetitive loop not unlike other games it does an excellent job to make sure there is not any unnecessary repeats. It has excellent art and though the dialogue can feel to me as wordy the story does well to invoke emotions other then the horny ones. Overall an excellent game that I would urge people to try. Looking forward to what the developer has next in store if it is of this same quality. A complete play though took me approximately 14 hours to complete.
I wasn't expecting much on download but I was pleasantly surprised it was a fun experience going through the game seeing all the slow progress made with Tatsumaki every interaction was extremely nice and the pillow talk was very cute and heartwarming and I'd hope to see another game of similar quality in the future.
Yeah it deserves its praise. Pacing was good. The RPG game portion was entertaining and varied enough and it didn't overstay and bog everything down. I'd say the only thing that would have made it perfect is animated scenes. Great job. Going to look into other projects of this Dev and drop some cash as I think the effort was deserved.
This is hands down the best game I've played on this website, it does everything right. The dialogues are absolutely fantastic, the way Tatsumaki talks to the MC is fantastic and I've actually grown attached to her in a way. 10/10, best game on this website by FAR.
Not really a one punch fan but still very much enjoyed this one. Great art, well written dialogue, engaging rpg mechanics, good use of music, wide variety of Tatsumaki scenes, choices that were both meaningful not overly punitive. You can tell this was made by a real fan and a talented one to boot. Very rare. The only notable shortcoming is that the game was a bit too obsessed with Tatsumaki at the cost of everyone else. There were a lot of interesting characters I would have liked to get more time with. Gobbo, Shark, Kitsune... Some like Bishop didn't even get a proper scene. Whereas others we're relegated to "simulations". Even her sister gets entirely forgotten in the epilogue. I can appreciate that Tatsumaki's the focus, but it was suffocating at times. The constant fawning over how awesome she is by MC in dialogues gradually made him less relatable. And the rest of the cast just weren't treated with enough respect. Not given enough time to act as even a proper tatsumaki pillow talk palette cleanser. Striking a better balance between Tatsumaki and the rest would have pushed this game to the next level. Maybe giving a select few a more meaningful Tatsu-approved secondary relationship. Still overall great game that I would recommend to one punch fans and non-fans alike.
I didn't expect much from this but it was pretty good. Putting the obvious fanfiction parts aside the writing and art are both well done, the scenes are really nice, and the over all story is nice. There is some grind towards the middle but there's no actual rush and the required combat scenes are fairly forgiving. The ending is somewhat lackluster which was mildly disappointing and there probably could have been a few extra scenes but this was a much better experience than I expected.
Very cute game. Good music, pretty funny, and an interesting story. Only caveat is that I thought there would be more scenes with the sister. I was really hoping for a throuple but oh well. There is also a lot of content, so I just skipped through a lot of the patrol stuff.
Really liked this game, one of my favorites now -great art and scenes -the story fits into the OPM world really well -good writing - felt really fitting with the character for main girl -not too grindy
Sadly, it is a mediocre work, and the word mediocre is what defines all of its aspects except the art, which is quite good. Dialogues? mediocre. Story? mediocre. Combat? mediocre. Tatsumaki is not Tatsumaki; they even change her backstory with Blast for some reason. I almost never skip dialogues, but the post-sex conversations in bed with Tatsumaki… just remembering them makes me sleepy. The MC is bland, and an alchemist…? xd If it weren’t an OPM game with the two psychic sisters, it wouldn’t even have half the score it has. It’s a shame. I don’t recommend it. I’d say I don’t even recommend it to the biggest OPM fans, because like me, they’ll be thinking the whole time: who is this person who looks like Tatsumaki but behaves like an idiot from a B-movie.
