Rêvivarium
A god game where you care for nature and help it come back to life. Currently in development.
You start with a barren land
Everything is connected. Wake a volcano and the ice will melt. Carve a trench and water will flow. The world reacts to everything you do.
Every problem has many solutions
An oasis needs water — but the nearest source is on the other side of the map. Do you push clouds with wind, or melt a distant glacier, or build a chain of rivers? Each challenge has more than one answer.
Then things start growing
Drop a few seeds. Come back to find moss, bushes and trees. But not every plant thrives in the same conditions — you have to set things up right.
Coming soon
And someone moves in
The right habitat attracts animals. They dig, they build, they mess things up. This place isn't just yours anymore.
Why this game exists
In Rêvivarium, you are part of the environment, and you help take care of it.
It's a passion project inspired by games I adored growing up — Populous, Black & White, From Dust — and more recent ones like Terra Nil. A god game about restoring ecosystems, without domination, violence, or exploitation.
It's a solo project, developed in my spare time and still early. Here I share some technical articles and news about the project.

Frequently asked questions
Is all of this simulated in real time?
Oh yes! The entire world — water, wind, temperature, erosion, vegetation — is a continuous real-time physics simulation. Carve a path and rivers will flow; build a huge sand dune and wind will change its course; divert lava into water and you will make it boil. What you see on screen is the simulation running, every frame.
Is there any violence or combat?
No. Rêvivarium is about restoring and nurturing, not fighting. You wield powerful natural forces — volcanoes, storms, erosion — but always in service of creating conditions for life to thrive.
Who is making this?
I'm Thibault Jouannic — a web engineer by day, building this game in my spare time (and sometimes at times when I should definitely sleep instead). It's a solo project that grew from a prototype I made to learn the Godot game engine.
When can I play it?
The game is still early in development and there is much to do. I did create this website so I could gather feedback and find who could actually be interested. Subscribe to the newsletter if you want to get news from the project.
What platforms?
Right now, it is developed for PC — Windows and Linux.
