use arrow keys for red. use w,a,s,d, keys for green. destroy your enemy with the aiming device. red aiming device controls 7,8,9,0, green aiming device controls 1,2,3,4. if you want to play again press the green flag you get the 1st point for defeating the enemy tank the second for playing again. the game keeps track of your wins & loses.
I challenged myself. :|)
