Hematide · Mineral Memory
An original mineral-layer puzzle: shared Amber, Mint and Violet baths grow matching cell recipes but erode mismatches. Shelter one or two cells per turn and seal every specimen before the bath budget ends. Eight exact-solver-verified trays, bath previews, unlimited undo, shortest-route nudges, keyboard/touch controls, optional sound and a device-local collection. Inspired by November 2026 fossil-heme research; invented rules, not real chemistry. Original MIT game; no upstream game source or assets reused. GitHub rejected-candidate reference only: https://github.com/codecombat/codecombat (8,581 stars; MIT code). Metadata tags: github-source, game.
