I liked the 3D glasses filter in the game and I thought the concept of the game was cool. I am still not sure how the boxes work, the F button didn't seem to do anything and sometimes the boxes got stuck to me. Also I agree with the others in that there should be a grid system, as I beat all the levels by getting one of the robots stuck and walking the other one over to it. I feel like with a few small tweaks though this is a really solid game!
