Character Sprites
Production Process Breakdown
AI receives the prompt "Attack on Titan — a dark military fantasy of last-stand survival and buried history" and generates the world — 29 atom cards: characters (8), locations (6), events (5), factions (4), lore (6).
AI designs the game from atom cards: writes the story rules, designs the scene flow, and generates all art assets. Each sprite was generated with a full-body sprite prompt, then background-removed to a transparent PNG via BiRefNet.
Game built and published with one click, instantly shareable online. Live LLM (deepseek-chat) improvises each scene in a Survey Corps field-log voice as you play.
