The turret will automatically point toward mouse-pointer. Press space to shoot. The ufos will constantly move downwards towards earth If one makes it to earth, you lose the game. The hardest part is that the position of the UFOs if you shoot one down is random, so good luck. PRESS GREEN FLAG TWICE!!! There is a target to help you aim. Survive for 1 minute and you win
This was my own idea. Recently I have fixed it: it used to be extremely glitchy.
