Defeat Set:
When facing Set (the God Of Darkness), dodge his flame thrower attack and his killer robots (which cannot be destroyed). Then, double jump past the energy walls. Next, hit the red ball on Set's forehead. When he goes into the lava, stand on the circular platforms around the battle arena. While Set is in the lava he shoots out tiny fireballs which explode into waves of fire. Dodge them by double jumping over the waves. Repeat the process until he is defeated. Note: the second, third, fourth, fifth and sixth time, he also he shoots out balls which turn into lava puddles which stick to the floor for a minute.
