Very good implementation of the theme. Nice graphics and sound. Sometimes i got stuck on a platform, in Unity there is a Component called "Platform Effector 2d", where you can set an arc which lets players though the collider when jumping on it from the side. That could solve the problem.
But overall, great concept and execution.
PS. The first idea we had for our entry was also going in a similar direction. Basically a sidecrolling platformer where every move is only used once alongside with some nasty leveldesign like fake pitfalls that would bait the player into using his jump, just before a real pitfall appears. xD
