We essentially made our own level creator by just changing note pitch based off of the height of a block. But, allowing the player to make their own songs/levels would be really cool! Thanks for the idea and the kind words!
The bug you mentioned is definitely one we found, something to do with the block collision pushing you outside of the wall detection zone. Sadly we never got around to properly fixing it. 25 loops is better than me, but Shock9616 (the programmer) averages around 10 lol!
