I played through the whole game, and the entire time I was really impressed at the thought and time that went into this.
It actually made me have to think about the puzzles, rather than autopilot through like most other puzzle games of this type. I love the main mechanic, its something that I don't commonly see being used in such a satisfying way.
There's really nothing that I can complain about, other than how short it is, I would def play more if there was maybe a world selection, each with their own mechanics. Otherwise, the music is great, the art is great, the puzzles make you think, and the mechanics are so satisfying once you get the hang of them.
