Double-tapping to run? You can dash by pressing D.
I've already got an fla sitting around on my desktop with a double-tap example, I am using CS3, I think I'm just using getTimer to check the time between hits.
Your sword doesn't grow, it just upgrades itself, there's going to be a shop where you can use coins that you get from dead zombies to upgrade things like your sword, idk if we're going to let you increase your skills like health, damage stuff like that. We havn't decided on anything about that though.
Um, so steroid zombies come after 1 minute. Barrel kills any enemies in range if you blow it up, and hurts you pretty bad. Steroid zombies can only be hurt by you after they fall down from chasing you too long. You're special attack kills an enemy in one hit but takes away half of your energy (it regenerates though).
