I liked the game. I haven't finished it, but that's primarily because I don't know what to do after beating the red boss in the dungeon.
When browsing through the files (the game package), I only saw a couple H scenes, I am hoping that the game is still under devolve; I like the the game itself and the sister thing is just a plus (I enjoy the actual game, its different than a lot of H games that are either just story boards or boring games, this one was more of a game youd get on a DS with some H).
If you're looking for a new game to try I would grab this one but be warned that the game play isnt straight forward and doesnt feel complete.
