just a little side note, mages (sad that there is only 1 magic casting unit :( )do not heal friendly units unless they are within range of an enemy. Shouldnt they heal any friendly unit within range regardless of how far away the enemy is?
"Note that you do not need to click any outside links to earn this badge. " This is, in fact, complete bullcrap. Impossible to finish the game without clicking outside links.
got the NaN glitch as well in one of my many attempts to get the fire tower achievement. Which, i recon, is bugged and impossible to get. The idea is that you kill all first 10 waves with just fire towers. However, there are a total of 20 flying enemies in those and fire towers cannot hit flying enemies. Hence, since you only have 20Hp only way to get it has to be to buy some health, however there simply is not enough money (in the enemies) in the first 10 waves to afford the health increase which adds 20 coins to the price per waves. unless u buy it at wave 1 and dont ever buy guns and die on wave 2.
if anyone has gotten this achievement please let me know.
