Very polished, plays great, awesome graphics, interesting puzzles, neat mechanics, and even the level editor is easy to use (I made a level editor for my GTMK17 game, and it was so much harder to use in comparison). I do think the originality isn't as strong as the design, since I've seen this idea in a few commercial games (and also in this game jam as well). Still, everything pertaining to puzzle design and presentation is superb.
