I agree with dave, why is this game has way too lag? but anyways i think it deserves a 9/10 because only a genius can mix an RPG witha FPS and games like this, are pretty hard to find :)
I agree with thos 2 comments that talks about the circle thing, anyways this is a good game 9/10 because no one else haves a damn punk that it's talking with you while the game still loads :P
ok, here's a tip: Revenge waves are not the end of all, actually is the best opportunity to get tons of gold, when get all your army with all the health filled, attack the castle at 3/4 with all the skills ready, result = a victory, lots of money and you didn't had to kill an insane wave of enemies (thumbs up if you like this tip :))
i have done this game 4 times, each time with differents graphics, awesome in all the differents types of graphics, really a great game, i think the best shooting game ever 10/10
