Zombies Drank My Beer

This is the first game I ever finished. It's about 2 years old, so pretty much everything about it makes me cringe. Sometime I'll have to do a remake. Something with actual graphics...

Here's my original description, from way back in '08 when I was first learning GM:

What's manlier that shooting zombies with a flamethrower from a flying jetpack? Drinking beer while you're doing it.

This is a simple 2 player cooperative shooter/platformer
I made similar to Bubble Bobble, but with beer and zombies. You can play by yourself, but playing with a friend is way cooler (you will need a game-pad for player 2).

I don't plan on updating this version much, but I do want to make a sequel, so any suggestions or critiques would be helpful.

Special thanks to lateksi2 for the awesome music.
