Released 2026-10-12. 4 updates since release, the newest 2026-10-12.
Newest update: Found Their Feet (2026-10-12)
- Complete the First Steps tutorial and earn your first trophy—a leather-bound tome that marks your passage through the Thornwood.
Earlier update: First Steps (2026-10-12)
- Mother Brasswick now guides you through your first hours in the Thornwood, one task at a time, with a golden glint showing you where to go.
- Read the Compendium, meet Brasswick, gather herbs for coin and draughts, spend your first point, and learn what lies ahead—each step rewards you with experience.
- The guide sits clear on your HUD, text is larger and darker so you can actually read it, and you can skip ahead if you know what you're doing.
Earlier update: Fate's Accord (2026-10-12)
- Fate now respects a hero's background when choosing their class — a Sky Mage will actually wield spells instead of a sword.
- A background's magical nature overrides the race's; even a dwarf destined for the arcane will become a mage.
- Day and Night Mages no longer roll as warriors — their spellcraft is honored from the start.
Earlier update: London Expands (2026-10-12)
- London's cobbled streets and gas lamps now stretch to every corner of the city, connecting all 115 buildings.
- The walkable bounds have grown — venture further out and discover new districts previously beyond reach.
- New neighbourhoods have been paved and lit, doubling the explorable area of the city.
What players say
@yzykyl · needs work · 2026-10-12 · played 30 min · shown first by the maker: “The amount of variety you can get with each hero is pretty cool. I let fate decide mine and ended up with an Elven Sky Mage but no magic? I went with it but I had such a hard time early game. I could barely hit my revolver shots and even my melee—”
- @yzykyl replied 2026-10-12: “—doesn't hit much lol. Would really help if there was a clear direction for the progression of my character like a starter questline that teaches you the ropes as you play. A questline that both serves as a tutorial for the game and kicks you off for a better start.”
- @razanur (maker) replied 2026-10-12: “sky, day, night and nature mage seems to be working now. working on the quest.”
@lego · needs work · 2026-10-12 · played 4 min: “The visuals look amazing for a 2D MMO! Tho I was confused about what to do at the start and spent like 3 mins figuring out that I could interact with the Compendium and talk to Mother Brasswick lol. Also, some of the text is really hard to read”
- @razanur (maker) replied 2026-10-12: “working on the quest.”
