Stacking process is interesting, but the game lacks a real sense of urgency. Maybe if you had the screen slowly panning upwards, and if your tower went out of view you lost or took some large penalty, it would help. music is slightly annoying, sound effects will sometimes sound clipped or "compressy", and the background is a little odd. Animation and physics are surprisingly good, though.
P.S. you might want to change the name
