To start the game press the green flag, use your mouse to drag your cannon and press space to blow your ammo at the invanders dont let the invaders touch you or you blow up and its game over for you! When you die press the red butten and then the green flag again
I only fixed some minor glitches but otherwise this game is pretty good DO NOT SHOOT WITH SPACE BAR!!!!!!!!!!!!!!!!! computer only, left click to shoot your cannon.
