Art is brilliant, and the concept is fun! My main issue though is that the controls are a little hard to handle. Its also quite easy to lose the magnet and have to reset. Perhaps adding a button to swap the magnet colour, and another to recall the magnet would be good. I'd also recommend making the magnet non-collideable when being recalled - it was a little frustrating having to try get it back and then waiting a while. Other than that, I did enjoy it!
