walking: WASD
shooting: left mouse button
goal: try to reach the pile of gold without getting eaten by zombies

It's not really finished (I can't place Zombies so these are hardcoded) but it actually meets my definition of done:
-it resembles the mockup
-2 levels
-shooting zombies
-collecting items/powerups

-programmed in Java (Netbeans Project included)
-images created with GIMP
-programmed on Linux
