I find it funny how people can say a game sucks when they have a max level character. You obviously liked it enough to put in the time to level a character all the way to the max.
Saying it's a ripoff of DTD just shows how retarded you are. Besides using towers to defend your base against creeps, they have NOTHING in common! If saying that this game rips off DTD, then I guess Protector and Onslaught are ripoffs too.
