Great game, Loved the creative use of the theme, though id have to agree with some of the others, this does feel more like a physics demo in certain places. one small complaint is that the room stops moving when your mouse is at the edge of the screen, if the game could detect if im still moving the mouse in that direction and act accordingly, id say it would improve the experience a lot, as many times i tried to move the room to a certain position, but had to do some weird manouvering to get around this limitation.
Overall though, great work!
