Aphelion

Something happened to the crew of the Aphelion. You're what's left to find out.

You wake as a lone cartography drone drifting in a field of wreckage, with no memory of your mission except a pull toward something further out. Draw stardust from the static around you, chart the drift sector by sector, and piece together what happened to the ship you were built to find — through fragments of transmission left behind in the wreckage.

APHELION is a slow-burn idle exploration game about light, memory, and what gets left behind in the dark.

- Chart the unknown — Every sector you reach reveals a new stretch of space and a new piece of the mystery, recovered as short transmission logs from the missing crew.

- Grow your reach — Invest stardust into collectors, sails, and relays that deepen your passive and manual harvest, from a first flickering Solar Collector to a full Event Horizon Drive.

- Ascend the drift — Once you've pushed far enough, collapse your run into Starlight — a permanent boost that carries into your next attempt. Nothing you've charted is ever lost: sectors, transmissions, and log book entries persist across every ascension.

- A living star map — Watch your discoveries connect into a constellation that tells the shape of your journey at a glance.

No two sessions play quite the same — how fast you push, when you choose to ascend, and how much of the mystery you uncover before you do is entirely up to you.
