this was really interesting and fun! i couldn't figure out how to select the first level after completing the tutorial, but the tutorial was really well made and i think the concept came across well
oh shoot - yes I think you're not the only one thrown off by the menu. The spokes on the wheel allow you to select the other levels. There's much more than the tutorial and I'm sorry it wasn't clear!
cool - yeah the transparency change on hover for the buttons broke on web, which really didn't help. Even the easy level is hard for someone who practices polyrhythms, but hopefully a fun challenge! Thanks again for playing.
