A very cool game with amazing use of physics! I am a sucker for neon colours, so it got my attention for sure. It is a bit frustrating though. Unfortunately one of those games where deaths need to have their own high score...
Some comments:
1a. If having WASD why not also the cursor keys? I really wanted to play this using my right hand.
1b. WASD is nice and all, but when trying to manically dash, you may change a song you like, or a station, and then you die a couple more (or more) times until you find what you were listening.
2. I saw that you added the level at the beginning of the level. Well, you may need to add it at least in the pause menu as well. After 40+ deaths, I couldn't remember in which level I quit playing...
