Great...
Very nice, I kinda liked the idea in multi-player mode, which is instead of everyone having his own devil, both players control the same devil at once, and that adds more challenge in the game.
Graphics are pretty solid, your music and sound taste is simple, but nice.
Problem is it's kinda short, and there isn't much of a fun in the single-player, probably you must add more things, like some new targets which you must not hit because it makes you lose point or so, or at least add other modes, like say...puzzle mode or something like that.
And that's why I gave you only 6, sorry about that, this idea is so AMAZING but you must be more creative and, please devolve it more man, it would be better...and thank you!
