Cool bass
Great tune! I like the beat and could see it in a flash game. A few things I would do to make it better: One, start the song with the bass (cut out 50 sec of intro, though I like the cool sfx stuff you're doing, do it with bass), two, expand upon the song a little to make it about 3 min, and three, make it loop well. And maybe give the bass a bit more low-end power.
