Nice concept and good implementation. Really the main thing that makes this so hard to play for me is how hard it is to move the boxes, because of the low friction and because the magnet doesn't seem to active reliably. In level 2, the second box was also stuck in the wall and was hard to remove, not sure if that is intentional. The pixelart is nice and I really liked the element of moving the boxes without touching them like at start of level 2.
