These puzzles were pretty good. The movement system is just right, and all the general mechanics feel really nice to use. My main critique with the game would be that the levels are too easy, which is fine, but I think the game doesn't have much potential with only one magnet. The problem is, when there's only one magnet, you know exactly where you need to use it right away. In a game like Portal, there are many portal surfaces that make the user really think more than how to solve a puzzle but what the puzzle is in the first place, which I would love to see for a game like this. Otherwise, I really like the final puzzle. I feel like there are people who are going to complain about it, but you are introduced to its length right from the start (which was really clever to make the player go through, by the way), so missing that it exists is sort of the own player's fault. What I liked about this level is that it isn't apparently clear how the player needs to progress. At first, the button on the right looks like the solution, which is really nice design. Overall, the final puzzle was really good, and the other ones could have benefited from some red herrings or something along those lines. I'm especially hoping we see puzzles in the future with multiple magnets. I hope this helps!
