It would be awesome if the zombie's strength changed to whatever they were changed from
(example, tiny bug to zombie=very weak, Demon to zombie=impossible to kill >:)
it's easier to win the game if you just jump around the field over zombies for maybe about 10 levels and buy mainly exp, money, healing, and reload skill first. and buy new weapons right when you get enough money. Mines are good when your surrounded and I didn't find it as useful when you put it down before a wave. and~that's pretty much it! have fun!
