I don't quite understand how the controls work. 'S' to scale up and 'X' to scale down? If so, they're not working for me. I am running your game through wine on linux though. 

Nice idea! I was stuck at the moment of two boxes that need to be placed on top of each other, because it was difficult to put them like that when one had already fallen to the floor. Unfortunately, I forgot that you can reset the level...

Super cool concept! The presentation is great and the puzzles are very well executed. The controls need a bit of work, as I had to hold my hands in a really awkward position to be able to control effectively. Overall nice job!
