Amazing game! i actually ran for like 3 more minutes after collecting the final audio loop because the music was so good and the speedup made the game feel really exciting!
I have found a few bugs:
- Sliding inside walls stick to a wall and slide. you will go into it:

- wallsliding on regular walls
wallslide on a pink or green wall, and just keep holding space when it turns into a regular wall, you will keep sliding

it would also be nice if you added an animation from regular running to sliding as it feels a bit choppy
anyway amazing ultra cool game
