Chaotic... but cool
It's a crazy song, but I really like how the elements work together, especially the FX you bring in at about 0:28. The piano part is perfect - really makes the song. I think this would go well in a game, but only the right type of game. The song is somewhat hectic, so obviously you'd want it in a game that would produce that kind of situation (IMO). I only mention that b/c you said you were making it for your game.
Please give my song a listen if you ever have some extra time. Thanks!
