This ended my playtrough of the game. I got stuck in a wall and that made the music get stuck aswell. 
Okay so you have a lot of Convayance issues in your game. (Where do i go what do i do)
I think this game could be alot stronger if you have levels that are less Sloped and keep tightly with the more Squareshapes just for clearity.
It reads better and it's easier to design challanges if you keep to a structure.
just tidiying up things visually helps a alot.
theres a big save code bar in the browser though which is really strange.
