InnerSpace is an exploration flying game set in the Inverse, a fading realm of inside-out planets where gravity pulls outward instead of in and there is no horizon to fly toward. Created by PolyKnight Games, a team of seven that began as college friends and took the game to a successful Kickstarter in 2014, it trades dogfights and checkpoints for open skies, flooded ruins and the steady pull of discovery.
A World Turned Inside Out
Every planet in the Inverse is a hollow sphere. The land curves up around you on all sides, oceans hang overhead as readily as they lie below, and open air fills the middle of the world instead of stretching away to a horizon. It is a strange space to fly through at first, and learning to read it is part of the pleasure. Civilizations once flourished across these worlds and are now gone, leaving their ruins and machinery half-swallowed by water and time.
You arrive in the final days of the realm to help the Archaeologist, who is racing to recover the last memories of the Inverse before they are lost forever. Fly through ancient skies and abandoned oceans, piece together what happened here, and discover what the end of this place means for its people and its gods.
Flight That Rewards Curiosity
InnerSpace is not a traditional flight sim and it is not a combat game. Its handling is built around momentum and freedom: carve tight turns between ruined structures, ride the open air, then plunge straight into the sea and keep going, because your craft moves underwater as naturally as it does in the sky. There is no timer pushing you along. The game rewards slowing down, following whatever catches your eye and noticing how each world fits together.
- Relics of the Lost
- Scattered among the ruins are priceless relics, the final messages left behind by the extinct civilizations of the Inverse. Each one you recover and bring to the Archaeologist fills in more of the realm's history and nudges you toward what comes next.
- Airframes From Lost Technology
- Salvaged technology lets you build new airframes, each with its own abilities above the water and below it. The Hopper can stop completely mid-drift and carries a compass pointing to the world's center, while the fragile Glass Piano is a challenge-mode plane its developers describe as their hard mode.
- Skins and Progress Tracking
- The Archaeologist offers unlockable airframe skins, some of them designed by the Kickstarter backers who helped bring the game to life, and a relic counter in the pause menu shows how much of the Inverse you have uncovered so far.
The Demigods of the Inverse
The Inverse is dying, but you are not alone in it. Demigods still roam these worlds, ancient beings hoarding what power they have left and keeping secrets as old as the realm itself. Each encounter is part puzzle and part spectacle, and reaching a demigod often means studying the world around it first. The developers set out to make a game where a plane becomes a submarine and then dives inside the belly of an ancient demigod, and InnerSpace delivers exactly that. Fly carefully.
Ethereal Art and a Soothing Score
InnerSpace pairs an ethereal, colorful art style with a soothing electronic score, and together they give the whole journey a calm, dreamlike rhythm. Light filters through the hanging oceans, the remains of old civilizations rise from every curve of the world, and the music swells and recedes as you move from the open air into the deep. It is the kind of game worth returning to simply to fly, with no objective in mind.
Begin Your Journey Within
If you have ever wanted a flying game that values wonder over winning, InnerSpace is a rare find. Take your time, follow the open air, dive where the light fades, and let the secrets of the Inverse reveal themselves. Your greatest journey is within.
