Really fun! I really enjoyed this one! And it looked great and was very relaxing.
My only critisism was that the magnets clipped through a lot of the objects for me which made some parts very difficult (in the second level it took me a while to hit the lever because I kept clipping through the wall dividing the rooms) and made some puzzles skipable (I clipped straight through the wall a couple of times).
But apart from those few bugs to iron out I think you have a great game here!
