I really liked the visual work, but it's hard for me to rate the puzzle design because of the glitches. The boxes would clip into everything and fly around inconsistently, and at some points the model got weirdly skewed for me. If you do make a more polished version, I'd love to see a more consistent physics engine, and maybe give the boxes some more weight so they don't go flying away when jumped on. The pause screen also softlocked the game for me, I was unable to pause it or do anything after pressing the escape key and had to force quit the game.
