How do I play for more than 2 minutes?
I'm usually slightly above average or just decent at defense games, but to me this game seems near impossible. I can't attack the monsters that are attacking me, because the target will die, but if I don't, I will die! I can't even buy upgrades, because I can't live long enough! The weapons you start with fire so slowly, and no matter what I set the starting weapon to, I always get the same thing. There should be more than one difficulty setting, and if there is, I can't find it.
