Use right arrow to turn right, Left arrow to turn left, up arrow to go forward. Hold space to shoot, and you can switch between guns with 1 and 2. Orange zombies have 6 health and green have 3, the sniper (1) does 2 damage with accuracy and shoots slower and the machine gun (2) shoots 3x faster with less accuracy and does 1 damage You will also have money right now, but you will be able to spend it in future updates including a shop for a new gun and other things :D Hope you enjoy!
