A one-thumb arcade game with a sharp core loop

APHELION is a one-thumb orbital arcade game: you're a comet riding the gravity of stars. Tap to fling yourself free from orbit — you fly straight and latch onto the next star you reach. Time each release to thread drifting hazards and strike the core for a bullseye bonus, chaining links into a rising multiplier through a fast neon deep-space shaft. Pure canvas, works in portrait and landscape, no build step.
