repetitive and boring
While usually these kinds of tower defense(that I've seen) got a pretty good rating, I'm giving this a 6 myself
The game is extremely repetitive, and the game only continues after you click "Start Wave" button. It slows down the pace of the game, making it extremely time-consuming. You could've added autostart and fast-forward button so players don't get bored 1 minutes into the game.
And the game really only focuses on how you're making money so your tower don't get blown to pieces. Really boring, doing the same thing for minutes. There is little variety in itself(enemy, weapons, etc), if you have the money, you get everything
The graphic is good, no plot or storyline(could use some here for enhancement) but game execution, bad
