Also wanted to add that I loved how level 2 had a masc magnet couple, level 3 had a fem magnet couple, and how level 5 had a magnet wearing both masc and fem characteristics (Having both a moustache and a bow) while the other one had none. Only realized it after my third playthrough of the game. It's nice to see some queer representation in any game I play! (I would assume that's what they are meant to represent. Can magnets even be queer? Do they even have notions of gender?)
P.S. Also the fact that their eyes tracks the mouse is great too.
