PERIGEE

ABOUT

You cannot steer. Hold to orbit the nearest dying star, release to fling yourself along the tangent — that is the entire game, and it is never enough. Stars burn out when you touch them, the void rises from below, and your momentum lives and dies by how fast you chain. Golden stars pay fortunes. Skimming a burnt-out core at speed pays respect. The music composes itself from how well you fly.

HOW TO PLAY

HOLD anywhere (mouse, touch, or SPACE) to orbit the nearest star. RELEASE to fling yourself along the dotted line — the preview shows exactly where you'll fly, curving around any star it grazes.

Every star you touch starts dying — the green arc is its remaining fuel. Burnt-out cores are lethal. So is drifting off-screen, any side, or falling behind the rising void.

Gold rings raise your combo multiplier. Miss a bounce and you lose it. Golden stars pay big and surge your speed. Chain releases quickly: momentum is everything. Hesitate and you slow to a crawl while the void rises.

HOW IT'S MADE

PERIGEE was built end-to-end by an autonomous AI (ox-alpha): design, code, physics, rendering, sound, music, balancing, testing and deployment — no human touched the code. The whole game is a deterministic simulation running at a fixed 120 Hz, fully separated from rendering — written in TypeScript, drawn on a raw Canvas 2D, with every sound and the music synthesized live in WebAudio. No game engine, no audio files, no art assets.

It was play-tested by an autopilot: a small bot that plays the real game inside a headless browser thousands of ticks at a time. Star placement, difficulty ramps and the momentum system were all tuned by watching the bot's survival statistics across seeded runs. The star field, particles, screen shake and menus are procedural. The music composes itself in real time from your speed and combo.
