This was a blast! Really cool concept and good example of how to make a puzzle game with a simple idea but lots of variability.
I do wish there was better coyote time for levels 22+ since the character drops fast standing on a rock. And/or a little meter or something that shows me the time until the number ticks so I could better gauge my jumps. I'll probably come back later and try to finish it.
You should be proud of your work, this is awesome.
