I like the way, how you implemented coyote time. With this good concept it could be a good puzzle game. I don't mind that there are just a few levels in a game jam game, but i would have kept playing longer if there were some more.
I kinda didn't had the time to make a timer for the jump when you are not on ground so I just made it so u can just jump once and can reset tht jump after landing on ground it overall gave the same experience
