I got say, the concept is not bad, but this game certainly lack of polish.
First of all, there are lack of texts desc for basically everything, comparing to art side things, texts should not be that hard to do, but the creator of this game certainly didn't doing well on this.
Then, despite the short content of this game, this game is too wasting time on basically everthing but the sex itself.
You would spent a lot of time to walkthrough this game, but there are lack of memory room kind things, so you are unable to watch back the scenes except you save a copy manully.
The two ending are also quite lazy worked.
