Solstice Cipher: Routing Light to Crack Codes — A Puzzle Game for the June Solstice Game Jam
Short summary
Solstice Cipher is an optical puzzle game where you route light beams through mirrors, prisms, and filters to decrypt hidden words. Built entirely with Google's Antigravity autonomous coding agent—no hand-written GDScript—the game runs on Godot 4.6 with custom raycasting mechanics. The 15-level game demonstrates how AI agents can serve as lead programmers given architectural constraints in plain English.
