needs balanceing hardcore, maybe more gold per kill, or lower tower/upgrade costs, and definitly monster hp or tower dmg... i had the 2nd strongest tower on the 10th wave and even it couldnt kill something before it got out of range
im not trying to be insulting or anything, since i have no idea how to even start to make a flash game... but what would possess you to make a "game" with absolutely no point? O.o and how do people think its fun? O.o
