Very original and interesting mechanic! Shame that there are only 5 levels and 3 of them are basically tutorials, but the last 2 levels are pretty fun! They are challenging, but not unreasonably hard, and require some planning to solve and not just brute force, although level 4 is slightly longer than it strictly needs to be. I love the sounds and the music, they are very relaxing and fitting for a puzzle game. The sound effects perfectly matches with what the magnets and the level is doing on screen, with the soft and cute footsteps and the equally nice whirl that happens when the magnet the player is controlling switches. The animation is very fluid and the visuals are very clear and cute. It's a very nice little puzzle game with a great central idea, lots of polish, and thoughtful level design. My only criticism was that I wished there was more levels, otherwise well done to everyone involved!
P.S. I really appreciate the fact that the game allowed me to revisit any levels I wanted and keeps progress even after I closed the tab, really made replaying the game for this review much easier!
