Thanks for playing! I tried to put the information on the description of the main page, the only piece I left out was the type of tower that does more damage to the type of unit. But it's pretty much like for like. Mage will do more damage to Mage, Rogue will do more damage to Rogue. The barb does more damage to the minions and does an aoe, so by himself a single barb can take out all of wave 1 except for the rogues that run past him.
