I'm a big enjoyer of Netori games (not to be mistaken for Netorare games, since I ain't a cuck), and this one would've been a 5/5 if only it wasn't for the protagonist. The protagonist's mime makeup and personality was a huge turn off for me, hence I rate it 3/5 (2.5/5 if I could rate it that). The story wasn't all that special or unique either, just one of the typical hentai stories out there. It would've been 1/5 if it wasn't for the amazing art and animations, which are some of the best i've seen in most animated 2D games.
So, long story short, if you could tolerate the protagonist's unique characteristics, or ignore them completely, then you'll enjoy this game.
