Battle through zodiac constellations in KON21 — a retro pixel RPG with card duels, evolving creatures, and a living world powered by cellular automata.
KON21: THE ZODIAC WARRIOR
A long time ago, across distant constellations, the zodiac realms fell into chaos.
Ancient creatures now roam the stars — their forms evolving, shifting, and living through the mysterious patterns of Conway’s Game of Life.
Only one warrior can restore balance.
Will you master the sacred art of 21?
