Squarefolk

Squarefolk is a tiny turn-based 4X demo that runs entirely in your browser as a single HTML file.

• Procedural maps — same seed, same map (integer-only generator)
• Real fog of war — the AI plays by the same vision rules you do
• Move & attack in one turn, with flank / support / stance / promotion bonuses
• Siege warfare: break the wall, then enter from an adjacent tile to capture — and besieged cities can still raise defenders
• City economy: farms → population → upgrades (workshop / bank / wall), 4-tech tree, unit capacity = city level + 1
• Win by leaving your opponent with no cities and no units, or by eliminating a cityless remnant within a 5-turn grace period
• Spec-driven development: public rules document, 68 golden test vectors, 146 assertions

Runs offline. Desktop + mouse recommended. UI is currently in Chinese.
