Th econcept is cool, and the way you featured the them is interesting! I think that the jump should be a liitle bit modified. The player should be able to jump for a little amount of time, when you're not on the ground, as most platformer games do, and you also should tweak the colliders and the ground a little bit, so i won't get stuck in a little corner of a platform, for example make the bottom of a player a circle so it won't get stuck that easily. in rest, good job.
It would also be cool if you will check my submission.
