love it, I started with the last level to challenge myself and found that some of the middle levels I struggled with a little more. definitely think the hub world that you settled on is a brilliant way of handling the approach to non-linear progression.
the puzzles definitely seem like they revolve around the magnet more than anything else with the platforming complementing it rather than overpowering it.
someone mentioned below that running into the rotating walls slowing you down being a bit of a flow-breaker. it could be cool if the magnetic ones pull you towards them and almost catapult you off. can't wait for the next update!
