Background and Worldview: Viking warrior Liv must gather the power of runes to defeat Nidhogg, the poisonous dragon dwelling in the World Tree of Norse mythology. Players eliminate ice blocks bearing ancient runes (such as runes) to power up Liv’s battle axe, advancing one level of the World Tree with each victory.

Core Gameplay: Rune match-3 combined with RPG attacks. Eliminating attack runes reduces the dragon’s health, while defensive runes increase armor. Enemies will also interfere with the board each turn (freezing certain runes). This is a turn-based match-3 battle.

Features and Highlights: Character progression system, unlocking new Viking skills (such as Thor’s Hammer for screen clearing). Boss battles differ in each phase.

Visuals and Sound Effects: Norse icy plains and wooden longships, with glowing runes. Majestic folk music, horns, and drumbeats.
