Immerse yourself into this surreal adventure about being a Starchild lost in eternal space. Find your way again and glide with awe in near-zero gravity through the calming and glittering world of Cosmosa.

This is a small game about exploring the hidden beauty and endless magnitude of the eternal space. You are a Starchild lost deep within its heart and now taking the time to find your way to what you are. Collecting star fragments and find your kind again.

Developer Notes

Cosmosa was designed to be a small game focusing on elements of space but also ethereal and surreal elements. In this game, you have the ability to wander around but also jump high distances and float in near zero while collecting star fragments hidden across the many different areas.


  • open designed levels, free to explore at your own pace
  • easy to play, no time or difficulty limits, very easy and relaxing platforming
  • discover some beautiful and surreal phenomena of the eternal space
  • enjoy a long and calming cosmic soundtrack

COSMOSA will come to Steam, Nintendo Switch, Xbox One and Playstation 4.

Public Playtest


playtest title

Hey everyone, we want to invite people who are interested to play a test build of Cosmosa. Similar to an early development build, the goal is to have a small environment to play around and test specific features.

(so keep in mind this is not for entertainment, but for people who actively want to help)

Instead of playtesting on our own, we can get some real feedback from you and improve the game until release. We had this idea of making small playtests for a while and everyone who is interested is welcomed.

The focus of this build is the player and basic features of the game, including UI system, music system, and movement.

You can download the build here:
