Gameplay
The game plays as a Metroidvania as you take control of Brunnhilde, one of the famous Valkyries. The game sets you in Asgard as you have to speak to the portal god Heimdall, at the cost of Bifrost which you can collect alongside gold coins. You can use Bifrost to either gain access to other worlds or upgrade your sword and armor as you can use gold to buy items such as potions or to enter challenge arenas. The game also has collectibles called Yggdrasil Pieces that both reduce Heimdall's price to travel via Bifrost and when all is collected, unlocks the true final boss. The game also allows you to go to any world and fight any boss in any order with the exception of the first boss, the last three bosses (four counting Loki) and Pride (which all the other six Sins must be defeated first).

Trivia

 * The series mixes elements from various myths, despite that, the creators confirmed that so far, only the Norse gods exist while non god-like figures from other mythologies do exist.
