Ancient Beast by Freezing Moon and contributors, AGPL-3.0.
Observed GitHub stars: 1886. Latest commit: 2026-10-25T16:03:19Z.

engine.js adapts the damage formula from src/damage.ts: round base damage
multiplied by 1 + (offense - defense) / 100, with at least 1 damage.
This version uses one-hex creatures and no elemental masteries.

This is not the full Ancient Beast game. The creatures, three handcrafted
encounters, resource economy, movement engine, whole-side turns, opponent,
healing, hints, undo, saves, interface and art are new for this adaptation.
No upstream assets are reused.

All corresponding application source is provided in preferred unminified
