A developer built FREE AT DAWN, a historical survival-runner powered by Google's Gemini API. The game uses Gemini 1.5 Flash as an AI 'Dungeon Master' that dynamically alters physics, weather, and terrain based on player progress. Set on the night of June 18, 1865, the player runs toward Galveston to hear the Emancipation Proclamation.

This is a submission for the June Solstice Game Jam FREE AT DAWN is a dynamically generated, historical survival-runner powered by Google's Gemini API. Set on the night of June 18, 1865 in Texas, you play as an enslaved person who has just heard whispers that the Emancipation Proclamation was signed two years ago. The enslavers have kept it a secret, but the truth is finally spreading. Your goal is to run toward Galveston to hear General Order No. 3 read aloud at dawn Juneteenth . How it relates to the theme: The game uses the concept of the June Solstice the longest day of the year as a metaphor for freedom. The tagline is: "Survive the shortest night. Run toward the longest day." As you progress, the sky physically transitions from a terrifying midnight into the glowing sunrise of the solstice. You are constantly running forward. You must avoid obstacles while outrunning the enslaver patrols behind you.

The core of the game relies on Gemini 1.5 Flash acting as an AI "Dungeon Master." At every checkpoint, the game sends your progress to Gemini, which returns a structured JSON payload containing a historical dilemma and environmental variables. My custom canvas engine then parses this JSON to physically alter the game's physics, weather, and terrain e.g., rendering grass, water, or storms on the fly based on the AI's decisions. I am submitting this game for Best Google AI Usage . In Free at Dawn , Gemini is not just used to generate text or pre-render assets—it is the literal core engine of the game. It controls the weather, dictates the physical terrain the player must navigate, dynamically alters the physics multipliers e.g., mud slows you down , creates the narrative tension, and generates a personalized ending. The game logic and the AI are inextricably linked. Without Google AI, the game cannot function "Now it's your turn. Survive the night, make the right choices, and reach the light 🌅"
