Fun and original concept! It's really engaging figuring out how to get the ball to the exit, even if it is usually fairly straightforward.
I do wish some of the things in the game were communicated for clearly. Such as the wooden panel being movable, the intention being that the red magnet should come out of the box, not making certain walls on the bottom of the first level completely transparent since it's hard to tell that they aren't.
Moving the magnet around the corners also feels janky and definitely slows the game down considerably gameplay-wise
