Arrow keys or WASD to move, but that only matters when you have the light saber. You need to use the shop to deal with the robots. The tank shoots towards your mouse pointer, The land mine explodes the robots, The quad tank shoots in north, south, east, and west, And the Light Saber swings around and does a lot of damage.
Its back but the UI is better and the game is more developed with music that I made (still quite terrible:( ) and is still not amazing! There is a secret lore page! Make sure to note that the bots have linked lives so they can keep gaining life. Also you can win the game by getting $350 Sometimes it doesn't work the first time you press play so click the green flag.
