played 2 times with different endings. In the begginig of 1st playthrough I found game pretty creepy, expecially the heroine, didn't try to find everything, items or dialogues, so in the end the ending surprised me.
Playing second time after knowing the truth and trying to find everything and paying close attention to dialogues I found heroine pretty cute, with her reasons and all mistakes that she made giving out the truth about situation.
The game doesn't have sex scenes, only erotic images, but even without them it's very nice.
overall it's a small game, no more then 2 hours needed while trying to find and read everything there is, all items are easy to find, no grind, hints to puzzles can be obtained from heroine right away, actually it's VERY difficult to solve some of them without asking senpai for help because they are made so that you have to ask her for hints in the first place and as such nobody is going to reward you for spending hours and solving them yourself, don't even try unless you love puzzles, and find it rewarding just to find the right answer.
After playing it I have only nice impressions, so I'm giving it 5 stars out of 5.
