A fun cool looking TD game, but I have to agree with the others the only tower you need is the Blade. Make it more balanced and require several types of towers to win.
Only problem with this game is that it makes it seem like non-smokers are more likely to kiss you, when we all know chics who smoke are way bigger sluts.
Shield Bash with that stupid speed booster needs to cost more energy. I just get hit twice in a row by it if I am on my last guy and will always lose. Make it cost more so you can't do it twice in a row.
