Oh hey, I was pretty close to making something similar haha. Well done on the concept. I wasn't 100% sure what the exact goal is even after the tutorial (i yeeted all metal on the yellow belt, is that correct?)
As others have already mentioned, items get unstuck from the magnet a bit too abruptly. The mechanic in on itself is good (move slowly to avoid dropping them) but it was very hard to tell and a bit inconsistent when they would get unstuck. Cool game regardless!
