Enjoy this gameplay demo footage, showcasing an early look at the game! Please note that what you see here may change in the final release, and you may spot some bugs as the game is still in development.
There’s something magical about games that let you play god — not in a power-hungry way, but in a creative, hands-on, “what if I made a planet with a volcano and a few too many clouds” sort of way. Curiosmos, a cozy space simulation currently in development, invites players to do exactly that. In its free demo on Steam, you’ll sculpt your own solar system, experiment with gravity and atmosphere, and even spark life — though not without a few hiccups along the way.
The Curiosmos demo begins modestly, introducing players to a newborn star who just formed their first planet and needs your help nurturing it. From there, it’s all about creation and experimentation. You can form volcanoes, adjust environmental elements, and harvest frozen water from nearby asteroids — essential for developing your planet’s habitability.
Despite some early technical bumps (my mic decided to take a vacation, and a few asteroids met untimely ends thanks to overenthusiastic clicks), Curiosmos immediately shows promise. Its soft visuals and sandbox-like creativity give off the same relaxing charm as other cozy worldbuilders, but with a celestial twist.
Make no mistake: Curiosmos doesn’t hold your hand. The game encourages you to tinker, fail, and try again — a design choice that feels deliberate rather than frustrating. Figuring out the purpose of mysterious “clouds” or learning how to properly extract ice from asteroids becomes part of the fun.
Yes, I encountered a few freezes (both literal and technical — coding overloads, anyone?), but for a demo, these are forgivable growing pains. The core idea — shaping worlds through curiosity and persistence — shines through the rough edges.
The user interface is minimalistic, keeping focus on the space sandbox itself. Customization options are currently limited — no key rebinding, no save slots — but that simplicity aligns with the demo’s “just explore” attitude. Still, future updates with expanded settings and smoother resource handling would elevate the experience.
Even in its early state, Curiosmos has that special something — the charm of discovery mixed with cozy creativity. It’s beautiful, meditative, and surprisingly funny when your perfect asteroid mining plan goes sideways.
If you’re into space sims that let you learn by doing (and occasionally breaking things), Curiosmos is worth wishlisting on Steam. It’s the kind of game that rewards patience, curiosity, and a sense of wonder — even when the stars don’t quite align.
Curiosmos is available as a free demo on Steam. You can also catch my full gameplay impressions on YouTube, or join my 21+ cozy game streams at 10 PM EST on twitch.tv/checkpointvibes.
