Interesting idea which suffers from a lack of explanation. Almost stopped playing because I couldn't pass the tutorial, but then I checked the itch page for the game and saw that the magnetize key was mislabeled (it's actually shift, not r).
There's definitely something here, it felt great to be launched by the magnets in the second level though I'm not sure whether that was intended or just a bug. With some more work + the addition of some sounds and music, this could be a really fun game!
