JÖRMUNGANDR

Move: arrow keys, WASD, or swipe   Boost: hold space   Power-up: B   Fullscreen: F
You are Jörmungandr, the world serpent. Eat to grow, and don't hit the walls or your own tail. Apples are 10 points, runes 50, boars 100, and golden eggs make you grow by 2. Power-ups turn up now and then: the star is a speed boost with double points, the potion is a shield that saves you from one crash, and the lightning bolt stuns Thor. Thor runs away from you, so corner him for 300 points. To clear a realm, eat enough food and catch Thor at least once, then travel on through the nine realms. Every 30 seconds you get a boost. Lose all three lives and you can start again, or continue where you fell.
