Well well well, this is underrated.
Yes, the physics can be a bit weird at times. Like the 2-3 metal/screws in level "Magnet 3" that always goes up through the floor when I press the magnet button. Or the magnet going haywire when it goes through a wall or floor due to the chain.
But the concept? The level design? The models? The music? Now that, that's good. You all did a wonderful job and with some polish, I think this game could be absolutely lovely!
