Very cool platformer!
just a few points of feedback. The speed of the camera pan is a little slow, definitely needs coyote time for the players jump, and because your moving the players with velocity, they get stuck on the sides of platforms. A way to fix that is to give them a frictionless physics material and up the linear drag for the rigidbody, although you will have to adjust gravity scale, and jump force to accommodate it. (Im using the same method in my game)
Very cool though! I love the art and theme! :)
