Short little puzzle platformer.
I do have to be honest that I did not realize why I would sometimes float to the top of a level.
Getting the block to the desired location in the final level is also quite messy as you need to shove yourself into it midair when it's bouncing up and down incredibly rapidly.
I like that time was spent in making the visuals look interesting as well as music and SFX that are fitting the experience.
With some better player-directing and particle effects, you'd get something quite neat.
