tl;dr: this is a pretty "meh" h-game with some seriously wasted potential. It's held back by a terrible progression system and no way to reset progress, as well as the use of a single female character with limited customization options.
The good:
-Some great art, and appeals to a few different sub-fetishes, such as hypnotism and brain-fucking.
-A fair number of customization options.
The Mediocre:
-Really, really short. This isn't necessarily a bad thing, as not every game needs to be an 80 hour grind-fest, and I appreciate a game that knows what it is and respects the time of its players, but it wasn't handled particularly well here. More on that later.
- With the fair selection of options to interact with the female character, it's a shame that none of them go too deep. Your options for vaginal are "fuck with a tentacle", "fuck with an ovipositor tentacle", and a clit stimulator. Your options for oral are a tentacle or a tentacle that feeds her slime. She then gets a swollen belly until you have her shit the slime out, which is... A choice.
-Hypnosis involves an eye stalk staring at her, and for some reason preventing any other interaction with her face such as using the oral tentacle. The hypnosis tentacle also doesn't really make it clear that it's doing anything other than preventing oral, at least until you've had it sitting there staring at her for a while. As someone with a hypnosis kink, this is a bit disappointing.
- There is a decent number of customization options for the female character such as hair color, eyes, etc, and you can buy her stockings and gloves, but that's it. The deepest you can really go is having the same character with different color eyes and hair, and make the hair slightly shorter or longer. It would have been nice to have more options on body shape, skin tone, hair style, clothes, etc. The game makes it look like there are broad customization features by making the menu full of ways to customize small things in a lot of ways - for instance, I found myself asking why I have 6 different ways to change her pupils, but no way to make her tan or change her nose?
The bad:
-The UI is not great. The game is largely based around status effects (i.e. increased sensitivity, cum addition, mind-broken, etc) but the icons themselves don't say what they are. There are around 40 of them, and you can turn them on or off on the fly. The problem is that each one is just an icon, and doesn't list the name or effect. To find that out, you have to go to a different sub-menu that lists those debuffs, then go back and find the icon that matches the list you had just looked at. The icons themselves are pretty non-descript and don't do much to help you figure out what they can do - for instance, multiple icons are just a series of hearts of varying numbers, sizes, colors, and arrangements, which correspond to completely different effects.
-I touched on the game's length earlier, but a big issue is the rate of progression. You earn currency by reaching certain milestones, leveling up body parts up to a max level of 5, and causing orgasms. The game lets you manually move your mouse back and forth to move anal and vaginal tentacles, and you get the currency ridiculously fast by moving your mouse rapidly. It also features an auto-thrust feature for those who aren't looking to have a mediocre H-game cause a repetitive stress injury, and even using that you get money so quickly that the in-game "shop" is really more of a way to turn on upgrades than any kind of a progression gate.
-Along with there being only one female character, there is also only one position. I'd imagine that it would have been a challenge to implement more, but it's still a real shame that there isn't any variety there.
-The biggest miss here is the lack of replayability. For a game that took less time to 100% than this review took to write, you would think they would have a "new game" option, but the only way to start over is to find and delete the save data for your game, which is actually insane to think about. You can use the hypnosis stalk to lock her sensitivities to level 1,and you can go and manually click each icon for status effects to disable it (why do japanese H games love repetitive stress injuries so much?), but to re-progress her status effects you would need to go back and re-enable them one by one. Which is to say that there is basically 0 replayability on a game that, even taking is as slow as possible, would take roughly 20 minutes to fully complete.
