Use arrow keys to move the green tank, down arrow to shoot. Use wad to move the blue tank, s to shoot. Use space to reset and go back to menu. At 100 points you win.
If you have any ideas for what is should put in the game next please comment down below. I have added bullets thanks too @supercoder421. (he helped me) I have added a start screen and three levels. Now it is harder to move through walls. Now added level four Broke game will take a while to fix levels 1, 3, and 4. Fixed levels 1, 3, and 4, but also took out the moving level. Weird bug where when you shoot out of the green tank, the blue tank will move back, I don't think it happens too often though.
