got the makings of something really good here. far too simple though. i just played to get the badges and did so using only spear and boulder towers with a couple arrow towers, and didnt even realize i could upgrade the damage/range until the end of the last lvl. and the only skills that seemed to have any relevance were the gem and gold increase.
