Nice work with the platformer character controller. It had a lot of mechanics with the double jump and wall jump.
Level 4 was your best level. It was the level I completed the fastest and was in the flow.
I feel to be a 'fast-paced' platformer, requires some time pressure. On Levels 1-3 I was taking my time and going quite slow, it would be nice to have a cat chasing you to add a time pressure to platform fast through the level.

Also I got stuck here if you wanted to test it out and try to debug.
