Your aim in this fantastic and highly addictive game is to type the word that appears below each enemy and press "ENTER" KEY to fire. If the word is spelled correctly the enemy will be killed. There are 2 powerups in the game. The Fullhealth power-up, it will not disappear so type it when you really need it. And the Detonate power-up, it will destroy everything on the screen (even the fullhealth power-up). Good luck!
