Oooh, nice puzzles!
Main observations so far: I love the chunkiness of the animations - objects slowly start moving and then rush into place with an inaudible slam - but I do feel a bit frustrated at the start of levels having to wait for the magnet to arrive and pick it up (them up? what are the magnet's pronouns?) manually every time. I kind of wish that the magnet would fall into the robot's hands as the level swipes in so I could just go immediately upon resetting a level or returning to the hub. (Loved that in Celeste, where "start running instantly" was always a correct timing for timed puzzles.)
The feel of resetting a level is good, though - it's not instant but it's quick. Which I appreciate, because I had to do that a lot.
