I really liked the idea of the only mechanic being able to move certain objects in the world, and as you progress, expanding the ways you can do it. Also liked the little visual effects you made and the music. Pretty impressive for something that you only worked on for a couple of days.
I think my only complain would be that, because of how everything worked, puzzles/areas would sometimes take a bit too long to complete, even after knowing what to do, which was a little bit annoying (but still, a very minor complaint)
