I really liked the concept for this game. BUT!!! Ultimately it is very frustrating, even when I build the worlds most perfect tower eventually it starts to sway and nothing can be done to stop the swaying until the tower starts to split and fall. If weight distribution is the reason why this happens, then there needs to be less brick variety so a more stable tower can be constructed.
This could also be combated with brick density in the shoppe or something similar that would help prevent swaying. As of right now though, I can't get past lvl8 and the 600 mark.
