Use L & R keys to move, up key to jump. 1 key to use Saber Spin, which makes you impervious to damage, and while the Dark Wizard is touching you he will be damaged by 100. 2 key to use Saber Throw, which sends your saber flying like Thor's Hammer that damages the Dark Wizard by 100, but you are not impervious to damage, so jump when something attacks you! 3 key to use Force Attack, which lasts for 2 seconds, so it does 200 damage. Avoid touching the Fireball or the Dark Wizard himself while you're not using any attack or while using Saber Throw, or you will lose 5 health each half second, and you only have 100 health, while the Dark Wizard has 3000!
Thanks to MIT for the book that made this happen!
