I like the flowy jumping, this part you really nailed.
The colliders tho... they are really unforgiving, additionally sometimes hitting the killing stuff didn't kill me? (coin and red part). Level 2 waiting was a bit annoying, as I couldn't zoooooom in a speedruny manner.
Overall cool game, I passed it :3
I didn't even try to go the other way xd
So ye, good job!
