A decree has been made: all worlds must be purged so life may begin anew. Play as the legendary Norse Ouroboros, sent down from the heavens to cleanse Yggdrasil - the world tree - of all beings.
Encircle your enemies to devour them and grow longer! Each foe behaves differently and offers new challenges. Take down bigger and bigger enemies as you grow longer and demonstrate your fearsome power by leaving none alive.
Travel through five beautiful worlds, each accompanied with a myriad of unique creatures, a breathtaking score, and challenging gameplay.
Without a fight, there is no true victory! Bosses of different worlds possess unique powers. Defeat each one to truly cleanse the world and progress to the next.
