Outer Helix Idle is a 2D space-fishing RPG. You're a freelance pilot for the Outer Helix Exploration Authority. They give you a small ship and a gravity rod and point you at four planets.
Each planet has its own look, weather, and ecosystem. The Helix Shallows are calm. The Orbital Reef hums with magnetic tides. The Void Trench is deep, dark, and full of things that shouldn't still be alive. Out at the Nebula Verge, the Aetherwhale breaches the gas clouds.
When something bites, you drop into a tension-bar minigame. Hold to reel, release for slack, keep the marker in the moving green zone. Every species fights differently, so what works on a Drift Minnow won't land a Void Leviathan.
Back at the Docking Station, harvester drones keep working while you're away. Come back later and there's a payout waiting. Upgrade the station, level your pilot, and feed Cores into an upgrade tree that keeps scaling.
Your catches go to the global leaderboards automatically.
