How did you choose to implement the Theme: Northern Saga in your game?
I explored various aspects of wyrd, not only from Götrik's perspective but also from those around him, using a raw approach focused on violence while respecting the theme's ambiguous morality. The game includes multiple routes featuring blasphemy, explicit textual violence, and profanity, and is therefore recommended only for players 18+.
I would like to emphasize that the experience proposed here is that of a visual novel, it has a lot of text and dialogue.

Did you implement any of the optional Bonus Challenges, and if so, which ones?
Yes, 2: Valkyrie and Runes of Power.
