not bad
controls where a bit hard to get used to (arrow keys work a lot better) and coins are pointless. here are a few things i would have liked to see in the game.
1. upgrades: who doesn't like upgrades. examples, stronger bat, move faster, ect.
2. be able to move into the fray. being stuck on one line is a bit restrictive. open up and allow the player to get into the action!
3. aggro. have the zombies "attack" the guy, i mean, for crying out loud, THEY WANT BRAINS!!!
that about sums it up. not bad for this try. i am sure if you take this skill and what most of the people(who leave usable feedback) the next game you put out will be a home run (yes, pun intended)
