If it's bug fixes go for it, I can provide a special link to re-submit, but please don't go adding new features/levels/etc. I plan to do the same with my entry.

My problem was that the instruments file was completely wrong. The drums were tonal instruments and the instruments mapped wrong. So the only change is in the music. Due to the last second rush I played it in on my piano in a single run as a spaceholder. It became permanent ;) If I could get the link I could submit a new copy.
