It's from the same creator of Teaching Feeling so I got into this one already hoping for quality.
Although short, the game possesses that classic sense of character progression that this dev is so famous for. You feel your bond with the girl slowly becoming stronger as you see her go through numerous stages of appearance and affection. You feel a personal attachment and you start caring about her.
Apparently there's more than 1 route but I got the happy ending and I'm really satisfied. It took me a little over 20 minutes to finish the game and overall the story is simple but good and believable (as far as mutant insect/tentacle/reptilian/human girls go). Beware, though. The game has no CG sex scenes. There is nudity, of course, but no fucking on-screen. And don't worry, there's no monster stuff here. All of her functioning sexual body parts are 100% human. TPA.
If you like a good story with an original plot made by the same creator of Teaching Feeling, look no further. The game is short but it's worth it.
