Very clever mechanics for a platformer. I like this interpretation a lot. Well done.
The sounds are fun too, but I wish it had some music. Seemed to me the second part of the game got cut right when a new mechanic is introduced, plus I found the game to be super short, so maybe you should work on a post-jam update to implement those mechanics 🙂
Not a bad entry for a 3-day jam, good job!
