I posted on your Reddit post as well, but this was a really nice game! It will need some more polishing, but overall, pretty smooth!
Some of the jumps are a little unstable/unreliable
The level end ring was confusing at first, you have to hit the ring and not the middle of it
I don't remember how, but I actually fell out of the level at one point.
I was able to beat your speedrun!My record was 1:06!
