About Perihelion

What is Perihelion about?

PERIHELION — Orbit Dodger. One tap switches orbits. Graze the debris, build the multiplier, survive.

A one-button orbit dodger built with three.js for start.ng. Tap, click or press Space to switch between the inner and outer orbit. Skim past debris to build a multiplier (up to ×8), grab lime core shards, and survive as long as you can.

In dev builds the game is on window.game for poking at from the console.

start.ng serves the committed dist/ folder and never runs a build, so rebuild and commit dist/ before pushing:.
