Soundtrack + Softlock Grass Fix

This small patch update does the following;

• Fixes the dreaded Softlock Grass present in the challenge stages
• Made the AYE enemies larger and more visible
• Moved the AYE enemies around in Drops to be more fair to the player

You can also now download the remix soundtracks found in certain levels. I didn’t compose any of them though, so the folks who did are credited in the songs’ metadata.
