This is a pretty good concept, and a fun puzzle game!
That said, it does feel like it was designed for a larger visible area, or at least a Follow command that treats walls as slippery (one of the puzzles in level 1 is just ?????, I might just not have the mind for it, but for me at least this is coming on pretty strong for a first challenge).
Also there's zero indication that boxes just don't work anymore on the same puzzle in level 1.
