Great level design, at first my thoughts where "I've seen a few games do this mechanic" but then you introduced the rotating platforms which was interesting enough of a mix up and varied the game significantly. 

Later I was just trying to do the levels with as few platform rebounds as possible just to challenge myself.

Very well done. 

Pretty good idea but it could have used more polish.

Wow! It may be simple, but the puzzles are really challenging and fun! I also love your menu screen and "tutorial" as you play.
