About this game
A heartfelt action-adventure about courage, friendship, and inner fire.
Explore vibrant islands, battle mythic beasts, uncover ancient secrets, and relight the lost Virtues of the world — as Mauri, an unlikely walrus hero.
🦭 A WALRUS HERO. A BROKEN WORLD. A FIRE THAT MUST BE LIT.
Long ago, the world was guided by ancient Virtues — Courage, Justice, Temperance, and Wisdom.
Now those fires are fading… and something dark is stirring beneath the waves.
After a carefree night out, Mauri’s best friend Touko vanishes without a trace. That same night, Mauri is visited by a powerful vision: the Wise Walrus Wizards appear to him in a dream, warning of the Black Tusks — a mad cult spreading across the Walrus Islands, twisting minds, hoarding power, and hunting the legendary Secret Walrus Fire.
You play as Mauri, a curious, stubborn, big-hearted walrus who never asked to be a hero — but may be the only one left who can become one.

Explore mysterious islands, help strange and unforgettable creatures, battle towering bosses, and uncover ancient secrets in a humorous, tongue-in-cheek 3D action-platform adventure with light RPG elements. Expect lively NPCs, meaningful quests, hidden paths, collectibles, and secrets everywhere — all wrapped in a warm, nostalgic style inspired by classic adventure games.
Beneath the jokes and charm lies a heartfelt journey about friendship, responsibility, and choosing who you become.
