Having a speed boost on perfect is kind of evil when missing your timing ends the run.

Do multiple perfects chain the speed boost - it felt like it kept getting faster.

Turning the classic zigzag into a speedrun with WR/gold/silver splits and a wrong-zag skip is a really clever twist, and the little glitch effect when you fall looks great. I died within the first second a bunch of times, ha. Maybe Practice Mode could be free from the start so new players can learn the corner timing before chasing splits.
