I'll give this game a solid 5-star review, despite it not being the Holy Grail of Porn Games that I've been looking for. But at least it's on the right track, half-way there.
You see, all you need to make a lightweight, engaging and instantly fappable lewd game which will not overstay its welcome is not a convoluted, long-winded story set in some nerdy SF or fantasy world full of irrelevant information and silly ass tasks to be completed in order to trigger sex 'events'. Just a plausible introduction into whatever the game is about, in this case corrupting the mind of yet another stuck up frigid biatch. And then on to the action!
The activities you're supposed to do here are quite simple, yet effective in terms of effort/reward. Your task is to molest (there's no other way to put it, although it's not something I fantasize about) a hypnotised classmate using your hands, dick and a progressively wider assortment of powered sex toys. Interaction with the scenes is done by mouse, with all two buttons and a mid-button wheel needed to operate properly. Takes a minute or two to get the hang of it but soon you'll flying as a pleasure tormentor of various body parts. The graphics are top-notch, with high quality effects, reflecting the poor girl's inevitable descent into wet and sticky depths of depravity. The H-voice acting is not overdone, which is quite rare in Japanese productions. Average playthrough time, while adjustable (you may connect your 'victim' to the toys and leave them turned on for actual hours) is just the perfect length and you can reach your desired conclusion in one evening sitting, if there's nothing better to waste 1/173010th of your life on. The intricate system of specific body parts erogenous sensitivities allows you to shape the girl's carnal profile in some interesting ways. Yes, it is possible to 'train' her to cum like a woman possessed from rough anal alone: no foreplay, no lube, no 'how was your day, honey?' - just straight to the A and she'll be pissing grool all over the bedsheets. Just put some effort into the groundwork first.
So, what more could you ask for? Well, despite the highly polished and complete looks there's still room to grow. All and all, there are only 4 scenes available, with 3 different positions in total: standing upright, laying missionary on the bed and sitting in a chair while trying to concentrate in the classroom. For a game which features quite a lot of anal, including wild assgasms, there are no positions which are most comfortable when engaging in backyard play: you cannot tell your mind-controlled girlfriend to turn around and spread them wide for you or lay on her stomach in the nurse room. Too bad. Also, there is no oral sex whatsoever, not even kissing or licking. I don't see why she shouldn't be able to learn how to deepthroat while motivated with a battery of vibrating eggs stuck here or there. And while she registers painful sensations from overstimulation, the game does not feature any elements of BDSM, be it impact play or bondage. It shouldn't be that hard to implement a masochism subsystem, where proper dosage of pain mixed with pleasure would slowly but surely corrupt the object of your desire into a cute, little painslut. Nipple pinching, breast mauling and rough anal is all the lewd brutality you can pull off. While the girl's chest area has two, well four actually, separate ero-regions (each breast and two nipples), her female organs even more (clit, vagina, G-spot, cervix and uterus), her backside is anus only and nothing more. Not even one buttock to slap or stroke gently, if you're that well-mannered.
Nevertheless, I wish more games had such complex sex mechanics, where manipulating these mechanics is the main focus of play, not just a gimmick thrown here or there.
