Visually very impressive for 48 hours. Other than the death, it looks quite polished as well. I'd encourage you to keep working on the music timing idea (even if it ends up being a different game), the idea of shooting to the beat is very appealing :).
I would definitely get lost a bit in the control scheme. Definitely hard to master (but happens a lot with limited control schemes). I got 7900 for my highest score :)
