I was never able to complete the first level, I was missing 3 bounces from the wall to jump. I advise you to use character controls that are NOT based on a physical model when making a platformer. It is better to provide good control over the characters in such games. I would like to have a sound volume setting (but many jam games have this problem). But the idea itself is good and overall good work has been done!
P.S. I remembered that they usually do a double jump, and I was right and was able to go to the next levels. The game doesn't say that I can do this, so I didn't realize it right away. Also, I didn’t immediately realize that I could push off from walls, this is also worth mentioning in the game.
