Thank you!
I was actually originally making them work like real-world magnets but the unity physics system didn't like it haha, when the magnets were too close, the force got so strong that they'd constantly wiggle around even with extremely high air drag. I'm definitely glad I went for less realistic physics thought because as you said, it opens up so many cool solutions to the puzzles.
My absolute favorite thing to do was watch people play, and watch them come up with completely unique solutions to the same puzzle. the ladder and lever in level 2 had so many cool solutions that I didn't even know people would do when I first designed it!!
