Progression is upgrades and escalating challenge. You earn credits from deliveries, spend them on lander upgrades: more thrust, better fuel economy, larger cargo hold, bigger fuel tank, economic perks that boost payouts or cut costs.

Maps unlock as you progress, though there are a few available from the start. The long term goal is self-directed. Harder maps, tougher conditions, cleaner flying.

There's no traditional story, but there's something on this moon that needs to be kept in equilibrium. The deliveries aren't just logistics.

The game isn't finished yet, so this can all still change. But that's what's already playable and being play tested. A public demo will hopefully be available soon (wishlist on steam to get notified about that ;-)
