The first platform jump is very annoying since slowdown time is so short and you can't know where platform is currently at ahead of time, so I had to pass it without slowdown by very precise jumping, took a lot of tries.

Suggestions: implement "jump buffer" and "coyote time" (if not already), make player move with platform when standing on it, make the level properly visible, so you don't jump into abyss.

Unity advice: always use FixedUpdate and linearVelocity to move characters, always enable Interpolation on Rigidbody, use LateUpdate on camera to follow transform position (not rigidbody position! the transform one is interpolated for use)

Fun little platformer, I really like the play with time in the zones, well done!

The sound of player is so funny, I did not expect it so, I think it is really good adding funny things, it make a better experience!. A nice game, with nice design!
