Too much bass? Not at all!
However, I do think it is a little loud in the beginning. I can tell that you've put a lot of effort into this one! It sounds very video-gamish, and I can virtually guarantee that if you get enough publicity this will be one of your most often-used songs in submissions. You did a great job with this song. :) More songs like this are a great idea!
Ah, and while I'm at it, can I suggest you (and maybe anyone else reading this review :P) listening to and maybe reviewing my songs if you've got some spare time on your hands? It would make my day. :)
