A good idea considering the theme and fun to play with! I do think that being given objects to stack instead of picking them would have probably made for a more interesting gameplay experience. The obvious option seems to be to just stack beer bottles to infinity (and beyond) haha. I don't know if it's just me but the performance was exceptionally poor, especially when holding an unplaced object it seemed. I had a rough time controlling the camera because of that as well and I would very much have liked to see scrolling by clicking and dragging.
My personal record was 235m of beer bottles. :D
