Released 2026-10-13. 2 updates since release, the newest 2026-10-13.
Newest update: Skill Cards (2026-10-13)
- hovering a skill on the bar shows a styled card like the stances: name, cast, cost, cooldown, what it does.
Earlier update: The Great Collapse (2026-10-13)
- When the final boss falls, the dungeon crumbles around you—15 seconds to escape before it collapses and sends you back to town.
- Start every class with two skills instead of one, so you've got more tactical options from level 1.
- The matchmaker now holds queued heroes for the full 30-second search window before filling empty slots with AI, so real players have time to join.

@moypi03 · loved it · 2026-10-13 · played 13 min · 1 heart: “I got 2 new skills to attack enemies, and my friends and I fought together against them. We even encountered a giant rat. The game was really fun, especially when playing with friends. I just wish I could choose other characters instead of only human”
