I liked this a lot better than the initial demo. Solid puzzles, not too difficult, but still satisfying. I personally had no problem understanding mechanics so I could focus on the puzzle solving without being confused.
Just a couple small critiques. I often ended up in a position where I need to reset the level, which I don't think feels super good to be forced to do. Also, the hub - the walk to each level becomes a bit too long, especially later on.
