Here is a porn game I can get behind.
Get it? Because she has a lot of behind. Her ass is huge. It's a porn game.
Please laugh.
Anyways, the character art is unique and strange, with Ayura herself being the only one I'd consider well drawn, but the animations are all fantastic and flow smoothly, and it altogether works largely as intended. The environmental assets are... well, bland and lacking, but that's not what we came for (HAHAHA). There's plenty of thematic variation in enemies from level to level, and at least one three-state animation (slow, fast, cumming) and sometimes two for each enemy depending on status effects inflicted on the protagonist. Some bosses or bonus events even have larger, more detailed animations attached. There's enough content here to get off from, and even a few relatively tame depictions of a couple dirtier fetishes.
The combat is fairly intuitive, although it may take a minute to figure out how to best take advantage of Ayura's moveset for each enemy or fight. The level design is... well, it isn't. It's largely just moving from left to right, from one fight to the next, occasionally jumping over traps or dealing with aphrodisiac pools. The game is mostly about the fighting; don't expect a sprawling adventure.
So what's the big deal? Well, aside from the fantastic animations, this game deals very, very heavily in themes of perversion and corruption. The protagonist has a stat for just about everything -- her bodily sensitivities, her passion, her masochism, how kinky she can get, etc. There are also "Talents", which functionally are achievements that make her more susceptible to becoming aroused by certain attacks or sexual grapples, including one which allows you to literally beg enemies to do what they want by twerking Ayura's ass at them. Every enemy affects each of these stats differently depending on the attacks they use, and status effects or talents can change how those attacks operate on Ayura. There's plenty of room to play around with her corruptability, and a lot of fun to be had just imagining how it affects her personality.
The game largely relies on sexual grapples and "game-over" rapes, although there is no need to reload saves, as being defeated in battle merely sends you back to the level selection hub. Regardless, it's a fair criticism that the game rewards losing rather than winning, but it's a personal decision whether that's a dealbreaker on this game for you or not. I found that it's easily forgivable with this game, since winning isn't hard, and going back to lose intentionally for the enemies you want is also simple. There's also a gallery room if you fully complete the game.
So, all in all, it's not bad. It is more of an animation showcase than anything, but it's a pretty darn good one. I'd say give it a shot.
