This wasn't a bad game by any means, and while there are aspects that could have been better, I believe that with time and polish this could be a much beloved game in the community. However, I will point out a few issues that I found....
THIS CONTAINS SPOILERS
1) Regardless of how you play the game there only two paths that it lets you go down. If I selected options that give me only affection I get one path, if I select options that give me only fear I get the other path. However, selecting options that give you an equal amount affection and fear, still only gives you the total fear result.
2) After you get to repeatable scenes with Yukina (following the total douche bag route), if you select blowjob, cumming both inside her mouth and outside her mouth results in an error page.
3) After the last interaction with Satomi, returning to her house and selecting reviewing lesson, will bring up the options as if you had selected talk.
4) If you do not go to the cafe in the evening to spy on Reiko, but you do go to the club on Friday, the scene still plays out as if you had gone to the cafe first. You are able to save and interact with Reiko, but the quest log is not updated. Meaning you could make this scene repeatable simply by not going to the cafe.
5) Definitely could use a proof reader for the English version. There are a number of spelling and grammatical errors, as well as problems with sentence structure and word choice.
