There's a really random bug in the game where holding escape will cause the race to end. 90% of the time, this cannot be interacted with, meaning it stays there until you restart the game. There is a small chance that you'll randomly be able to interact with it, meaning that if you're lucky and performing this bug allows you to beat a track (rather than it saying you lose), you can actually click to go to the next track.

If you combine this glitch with the level skipping glitch, whereupon spamming the button to go to the next level you skip everything, you can potentially beat the entire game in well under 30 seconds.
