Lovely game. Puzzle design and music were done well. I love the clean art style and the SNES-vibes from the sprites. Very, very cool take on the magnet theme!
Hopefully constructive feedback:
One of the puzzles I found a bit frustrating, the one with a platform in the middle and a switch at the top of the screen, with a minus block on the floor and a gap we had to get across ahead with a skinny platform in the middle. I eventually cleared that one after some trial and error in what felt like a ... sort of random way. All the other puzzles I felt were great (if not apparent after some inspection, solvable with some trial and error).
Even with a controller I found myself moving the wrong character at times. I honestly don't know how to help with this, and there was definitely a point where moving both characters felt more natural, so this may have just been the learning curve. A positive note is that it was fun enough to stick through the intial awkwardness of that. Maybe when one character is being moved and the other stationary, the moving character is highlighted? Again I'm not really sure how I would tackle that.
Again, love the concepts, art, music - really everything about it. Thank you for sharing!
