I don't understand how to get the Conservative Constructionist badge. I built my 33 block tower without losing a brick or deleting one but wasn't awarded. Do you have to finish the game without deleting one and have 33 still standing? Can't be... that would suggest that you have to place all 99 blocks. Hmm.
Very entertaining levels. Level 12 is particularly challenging - but makes it all the sweeter when I slowly make the transition from barely hanging on to going on the offensive. Love these games and really enjoyed Creeper 2 as well.
