666

666 is the sixtieth level in Jetshift, where players face off against Devil Demon. The difficulty of the fight depends on the difficulty selected on entering the level.

Battle
Devil Demon will stay idle for a couple of seconds before summoning a trident (which points directly at the player) and teleports to one of the three platforms.

In Nightmare Mode, Devil Demon will often take some of Glitch's star attacks and has a 1/3 (33%) chance of disappearing before summoning duplicates. The player must choose the right one in the group and must be quick, otherwise stars will fly at them.

Normal

 * Only teleports and summons tridents.

Nightmare

 * Can summon stars and cause himself to summon duplicates.
 * Intervals between attacks are short, rendering a bullet hell possible.

Tips

 * The duplicates are slightly transparent, so the player can tell the differences between the group if they look closely.
 * Shooting a Ninja Star at a duplicate will not make it enrage. However, if one hits the Devil Demon, the duplicates will disappear.
 * If you take too long to choose the right one in the group, stars will get summoned and the duplicates will persist until you do choose the right one.
 * Staying near a platform will increase your chances of getting hit, so stay near the left or right side to dodge the trident when Devil Demon teleports.

Trivia

 * 666 is actually known as the 'Number of the Beast' in popular culture, and is often associated with The Devil, hence the reference made in Devil Demon's character design.
