The First 15 Minutes of Jotun (Wii U)

Copied from MobyGames:

Jotun is a top-down action game with a focus on exploration and based on Old Norse Mythology. Thora is a brave viking woman who died ingloriously in a shipwreck. However, the Norse Gods have given her a chance at entering Valhalla if she is able to defeat the five Jotun who dwell in different worlds, all connected by the Ginnungagap.

The viking warrior has to make her way through different levels in order to collect runes which grant her access to the boss battles. By exploring the different levels, she is also able to collect blessing from different Norse Gods as well as glimpses into Old Norse mythology. The game uses hand drawn graphics.

The Valhalla Edition of the game is the name used for the later console version of the game. It adds Valhalla Mode, a boss-rush mode with harder versions of the jotun.
