The game is really fun! Some (hopefully constructive) feedback:
-I'm not sure why some levels don't start with the magnet already in your hands.
-It would be nice to not have to set the magnets polarity before checking it into a level select pipe.
-Small visual bug that the magnet travels behind the keys on the screens in the hub.
-The fact that some buttons are ramps is neat, but occasionally annoying for movement, because if you're on the wrong side of the switch you have to jump over it and then roll back onto it.
