The surface is no longer habitable. An environmental catastrophe has rendered the ground toxic, forcing humanity to seek refuge in the skies.

In UP TO THE SKY, players step into the role of a survivor tasked with ascending above the poisonous miasma that blankets the land.

Your journey begins in a desolate, dead forest, but survival hinges on your ability to climb. Utilizing giant trees, elevated walkways, and any structures you can find or build, you must ascend to secure safe zones far above the deadly surface.

The core gameplay loop revolves around gathering essential resources like rusted steel bars and scrap materials to construct your new home and establish a sustainable existence.

This isn't just about reaching higher ground; it's about building a future. Players will need to cultivate crops and raise creatures to ensure long-term survival in this vertical world.

The game emphasizes perseverance, with the mantra "falling is not failure — giving up is. " It paints a stark picture: "Below is hell, above is heaven — and you hang between life and death.
