The audio is good but might want to stop it repeating if you die as it overlaps a lot and possibly balance the volume down a bit. I *think* I heard other sound effects in there but could not tell over it!

Hitboxes may need tightening to your objects especially with platforming
Make the room transition zones a little bigger; can fall out of the world!
Not sure if intentional, but the black pillar in the starting room looks very impassable. Might need to make the platform extend a touch past it.
It has potential for sure!
