click on the green flag 2 times use mouse pointer to move and space to shoot, but shooting is limited for the boos fight, after the boss does its fire-Lazer-thing, shoot at him. do those three times and you win. don't touch the boss, rockets, and spikes. Good luck.
WARNING: THIS GAME IS NOT FOR ANYONE YOUNGER THAN 12 YRS OLD (EVEN THOUGH I AM STILL CREATING THIS GAME AT THE AGE OF 10 AND A 1/2) BECAUSE OF THE DEATH ANIMATION AND THE MUSIC.
