The rating is not lower because the bar is in hell for action H-games. The standards are so low even an experience as whatever as this one gets away with okay ratings because it was somewhat entertaining and not HORRIBLY poorly made.
Forgive my possibly small vocabulary throughout the review, English isn't my first language.
Skip to the last chunk of text before the summary if you want to see some thoughts that have to do with the porn part of the game, the rest is just my deranged ramblings about gameplay unrelated to the porn.
Starting this game, seeing some of the mechanics and the bullets, I was thinking "wait a fucking second... Is this fucking H game Enter the Gungeon? Hell yeah."
I was then promptly disappointed.
This game is whatever. It's one of the lazier attempts at this type of game that I've seen. It is incredibly basic and there is not much to it. It shares some stuff with Enter the Gungeon and I wouldn't be surprised if that game was a direct inspiration for this one (or Nuclear Throne but I haven't played that one sorry) but it basically stops at the basic mechanics like weapons, items, blanks, bullet based combat, and dodge rolling.
The game does not have you progress through any sort of space, even though I feel like there was a pretty good story setup for that kind of gameplay. Instead, you're stuck in one arena, progressing through "rounds" of enemies, with a reward after completing each one, and a boss at the end which ends the level. It's just boring I'm sorry, there's nothing that keeps me very engaged in this game. And it's not just this one decision, many games have done it right (you prob know which ones) but it's everything that surrounds it that makes it the main downfall of the game. Nothing feels like it was designed around it. Most enemies feel slow, not super actively aggressive, which shouldn't be the case in a game where you're in one room the whole time and there is literally nothing else to do but fight. Combat should be far more fast paced to keep the player REALLY engaged, it should be amazing, fun enough to carry the game. It isn't here, it was just okay and when it's the one thing that needs to carry the game because there's nothing more to it, that's a failure. Doesn't help that the player character has a ridiculously enormous hitbox for a bullet hell game, which is just annoying to play around especially since literally no attack feels properly designed around it, and I don't see any pros to it. Movement doesn't feel great either, just... fine enough I guess. It also doesn't help that I personally didn't find the game very challenging, health upgrades and recovery are plentiful enough that as long as you're playing okay enough you'll tank through your mistakes and win without ever dying, in my personal experience.
To tell the truth I feel like this game doesn't get the appeal of roguelites. I'm unsure if I can fully count it as one considering the levels system, but at the very least I can tell it's really trying to be one, or at least be like one. But the fun gameplay loop of a roguelite just doesn't work here. The combat is not fun enough to keep anyone coming back for more runs, it just kept me decently engaged for a single playthrough and I came out of it thinking it was whatever. The weapons, stat boosts and items are not interesting enough to keep anyone coming back either. And that's literally all there is to the game, it's THAT basic. It's not particularly good as a one-time experience and it sure as hell isn't good enough to keep anyone coming back for more runs once they win, since there isn't anything interesting to experience by coming back for more runs.
Finally, as an H-gaming experience it's also whatever, especially if you're good at the game, trying not to die, and want to experience the game's porn elements without failing on purpose.
The grab system is overly easy to escape and has no effect on gameplay- even if it wasn't piss easy to escape, getting grabbed by an enemy literally does nothing to you as far as I can tell. No damage, no nothing, just an endlessly looping animation until you escape. And it's like... Oh no, you "got caught"... but no worries, just escape when you feel like you're done alright? No urgency or sense of defeat at all. At least end it after the enemy cums, jeez.
Getting actually defeated by losing all health makes an enemy do the same animation and then sends you into a full game over scene with full drawings and stuff, and all the porn itself is actually quite good. This part would be all well and good if I found the combat engaging and challenging enough to actually die at any point, but I suppose that's more subjective (I think others do find this game hard, plus I think some other people don't mind dying on purpose to just see the porn) so I can see people enjoying this part of the game, but this is my review and in my experience this part of the game was also whatever. Even if the game was just harder so I just died more, I'd still wish the combat was also much better and more engaging to make my defeat and subsequent sexual humiliation that much more satisfying.
In summary, this game is too basic with little content. Its few basic elements are not great enough to carry the game through that basic-ness, and the gameplay is not, for me personally, engaging or hard enough to make for a good fucked-on-defeat experience.
