Generally, the game aspect of this game is full of minor design flaws and  far from polished. But even if you see this not as a game but as a art collection, it kind of worth at least 10 bucks.

For the theme and popularity, I must admit that squick fetish+corruption+transformation is a very niched theme, so the major public may not like this game. However, if you happen to be one of the dark minions, it is BLASPHEMOUS to give a rating less than 5 stars.
