Nice game!! It's nice to see this creative take on the theme ^_^
Some extra space for the boxes to move in general would have been nice. The box you have to swing into the first button is a bit too hard to get into place when you don't know what you're doing because it's difficult to space it correctly for it to not touch the floor or the ceiling. Also the boxes just after that can get stuck very easily when falling, because the holes are not big enough for them to fall diagonally x_x
Besides that it was an enjoyable game, would love to see it turned into a full game with more levels ^_^
