Here we go, a new level.
At once
I made this to showcase a couple of unusual combinations. For example, a door that you can only enter and exit once. It surprised me that the yellow magnet behaves different than red magnets with big blocks. I didn't know that. The puzzle itself may be short, but the solution is, in my opinion, interesting. Includes a small bonus arrow puzzle.
