I didn't think it was too bad
I don't understand why this has such a low score. It seems fine to me, although it certainly isn't one of the best I have ever heard. This didn't remind me of Crash Bandicoot, it actually reminded me more of Sonic the Hedgehog, probably because I'm just more used to that music than CB music. I thought this worked just fine as a video game loop, even if it didn't sound too original. I think you at least tried to come up with something nice. My suggestions would be to have more variety in the kind of instruments being used and the beats made.
