About this game

Short Description

A cubic spaceship has crashed on a distant planet. Gather blocks from the world around you, rebuild your ship with them, bring cargo back to base, and use it to build your tower higher and higher — until you can finally escape the planet.

About the Game

Build your ship from colored blocks, launch it into a dangerous world, and try to bring back as much material as possible. Every block you deliver becomes part of a growing tower, while your progress unlocks new ship capabilities and new ways to deal with the world around you.

But every new flight demands more decisions.

Moving a Single Block Can Change the Entire Ship

A block’s color and position determine what it does as part of the hull. Move just a few cubes, and the ship’s stats, shape, and capabilities can change completely. To reach valuable finds, you may have to rebuild your ship on the fly.

Flying Is About Making Decisions

What should you pick up? What should you leave behind? Is it worth going farther, or is it time to head back? Should you intervene now, or save your resources for later?

Manual actions consume a limited resource, so you cannot endlessly fix every problem. Eventually, you will unlock an autopilot that can take over some of the work, but its capabilities are limited too — and its decisions still come at a cost.

Your Ship Evolves Alongside You

As you progress, you unlock new abilities, upgrades, and ways to interact with your ship. They do not replace its construction: you still need to build a good hull yourself. How you use these new possibilities depends on the ship you have built and the situation during each individual flight.

The World Follows Clear Rules

The higher your tower grows, the more dangerous your flights become. Different hazards force you to rethink your usual tactics and ship designs. When you encounter a new Hazard, you can learn how it works and prepare better the next time.

Features

  • Build your ship from colored blocks whose properties depend on their position;

  • Rebuild and reshape your ship during flight;
