Not really for me
I have to give you credit for coming up with a game that's pretty interesting. The only problem is that I am simply no good at this kind of game. It is fairly unique, but it's hard to enjoy it when it's so incomprehensible. I think the graphics in this reminded me of the stuff by Dave (of "Retarded Animal Babies"). It was interesting how the character's design contrasted with the playing game. At least you have the oppurtunity to sell your soul.
I hope other people are at least able to beat this game. I guess I could suggest that you put some more detail into it. This is kind of like sudoku, in that some people will have tons of fun with it, but others won't be able to advance. The sounds are alright, I suppose. I could go on all day trying to fight the right combinations.
