Red Tank uses the arrow keys to move and the "p" key to fire. Green Tank uses "wasd" to move and the "g" key to fire. Don't get stuck in a wall. You respawn at the same place every time. Based off the internet game "Tank Trouble." (Go to www.TankTrouble.com!) WARNING: THIS IS JUST A DEMO!!! DISCLAIMER: I DIDN'T INVENT THE CONCEPT FOR "TANK TROUBLE." *Works better when downloaded.
