You got 3 options: Attack, Check, And Defend Attack: you attack the enemy, but after this the enemy will try to attack you. use your mouse pointer to avoid the projectiles and all stuff that appears on red. Check: checks the enemy attack, and defense. thats all. defend: you'll summon a shield. there is a chance you damage the enemy without even letting him do his turn. but meanwhile it could damage you the double. so be careful! defeat the enemy to WIN!!!
