This game would definitely win the category for the most polished itch.io page if there was one xD

So I'm gonna be brutally honest, there are a couple of big issues with this game:

• There's a game-breaking bug right at the beginning where magnets dragged onto the level will instantly disappear. You have to reset the level a few times before they will stay and stop disappearing when placed.
• The critical side-panel holding all the important bits should not default to being collapsed and hidden. I was baffled when I first played this game, because it disappeared so quickly that I didn't register it was there at all. Also on the subject of UI, the text for each level takes up a baffling amount of space, pushing the play area way over to the side all scrunched up.
• There was a level called "speed run", not sure what the mechanic was supposed to be, because all I had to do was move the pre-placed magnet to the other side of the screen, and then it was just a repeat of the very first level.
• There is a level where a big blue "S" circle is present in the center of the screen, and magnets I place on this level are large and immobile. It's not clear how or why that element of gameplay has changed, and it's very frustrating. 
• So far it's just been a succession of levels where the solution is "put a line of opposite-colored magnets" leading towards the goal, so I'm not seeing where the puzzle element comes in. 

The good bits:

• Music is nice
• I like the bloom and 2D lighting applied to the scene, it's very atmospheric

I couldn't get past the tutorial page where it describes how to play. There is no button to continue or close the page, and no keys I pressed did anything.
