Cool concept. I think what could be improved is that the farer away you are from the magnet, the slower it pulles you, and the time when the magnet pulls should stay the same. This way if you're really far away from the magnet it doesn't pull you back all the way to the end. Likeing the game!
Also: If you're using GODOT, you should should set the buttons' "enabled_focus_mode" (Enabled) value to "none" in the editor. This way when you click a button there wont be a blue rectangle around it.
