multi coloured square:can put any type of tower on there .. water tower shoots water to slow enemy down upgrades.. faster shooting,more damage, ice shots\hail shower (upgrade them)
So if you do make another version of this game add a pause button, maybe them attacking us and the other civilizations, a difficulty level and a speed button 1x 2x 5x?yeah this game brought to me to kongregate aswell :D and I rate this game 5\5 epic cool (>:D)..
