I liked the music and I liked how fast the character was.
- I would add a button that quits out of the game, just pressing escape to do exit would work.
- The character is fast but the accelerating feels a bit slow, that might be my computer though
- You can add a frictionless physics material to the colliders to make the player not get stuck on the block
- Since the platforms are small, make a shadow or something underneath the player that shows if they are above a platform.
