About InnerSpace

Your greatest journey is within.


In the final days of the Inverse, you must help the Archaeologist recover the last remaining memories before they are lost forever. Fly through ancient skies and abandoned oceans to discover the lost history of this fading realm, where entire civilizations have died, yet their gods still wander.

InnerSpace is an exploration flying game set in the Inverse, a world of inside-out planets where gravity pulls outward instead of in. InnerSpace began as a project among college friends and evolved into a successful Kickstarter campaign in 2014. After years of development, PolyKnight is proud to welcome you to the Inverse. Your greatest journey is within.

Features:



  • InnerSpace is a game about exploration, about player-driven moments both small and grandiose. Take your time, soar through the skies and dive through the oceans, and the secrets of the Inverse will reveal themselves.



  • Scattered among the ruins are priceless relics, the final messages from the extinct civilizations that once ruled the Inverse.





  • Adapt lost technologies to build new airframes, each with unique abilities to soar above the waters, and below.





  • The Inverse is dying, but you’re not alone. Demigods still roam here, hoarding what power they have left, the keepers of secrets as old as the Inverse. Fly carefully.





  • Featuring an ethereal art style and soothing electronic musical score, InnerSpace delivers a thoughtful, provocative flying experience unlike any other.

A quick note from the developers:


We started PolyKnight Games back in college, when we would meet after class to talk about new challenges in game design. We became fixated on one question in particular: "What would a flying game be like in a universe of inside-out planets?" To answer that question, we decided to put aside our career plans and form our own indie studio.

InnerSpace is not like other flying games. We want to reward exploration, both in terms of storytelling and the mechanics of flight. If you’re expecting a traditional flight sim with aerial combat, this might not be for you. If you like the idea of a plane that transforms into a submarine, then dives inside the belly of an ancient demigod, you're in the right place.

Please contact us on Twitter or the forums if you have any feedback at all, or if you just want to say hello. Thanks so much for checking out InnerSpace. We hope you enjoy the flight.
InnerSpace is a game of exploration that we must help the Archaeologist to recover the last memories that remain before they are lost forever. We will have to cross the skies and oceans of deserts to discover the history of this ancestral kingdom, where entire civilizations have disappeared but where we can still find remains of them and investigate them for our own benefit.

In the universe in which we will move, gravity acts towards the outside and not towards the inside, which will facilitate our exploration and offer us unique experiences. Take your time, soar through the skies and plunge into the lost civilizations where we will find powerful and valuable relics scattered among the ruins.

We will be able to build new fuselages from technology lost by the world, which will offer us unique capabilities, such as flying over the water or submerging in it. A unique adventure where we will live one of the most rewarding flight experiences, and all accompanied by an exceptional soundtrack.

Most common FAQs when buying InnerSpace for PC in digital format:

  • What is the key for InnerSpace on PC?

    It is a key that will allow you to download the game InnerSpace on your PC from official download platforms.


  • What's the best price for buying the key of InnerSpace for PC?

    As of 05/12/2025, in United States, the best price we have found in our selection of online stores that include the key for InnerSpace on PC is €0.57.


  • Why is the Steam Key of InnerSpace safer than the account format? See more

    The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download InnerSpace to your game library. The account format requires more complicated steps and is more prone to errors during activation.


  • What issues can arise when activating a Steam Key of InnerSpace? See more

    The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought InnerSpace, and they will provide a new key. You can also contact us, and we’ll help you out.


  • How long will I have to wait to receive the Steam Key of InnerSpace after purchasing it from a store? See more

    Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

    Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

    If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.


  • What guarantee do I have that the listed stores are reliable? See more

    At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

    In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
