This game is still being worked on I see there was a Jan 2021 update:

Long time has passed since the last update. I apologize to all the followers and as usual I would like to reassure everyone:the project is always under active development and lately is going fast! I did tons of improvements in the meantime improving graphics and speed, physics, terrain elements like trees, rocks, adding a very fast instances management and improving terrain definition and 3d clouds!

 

Dear All,

Long time has passed since the last update. I apologize and would like to reassure everyone:
the project is under active development and lately is going fast!

I stopped posting updates for two main reasons:
First, I was working on critical parts of the code which involved the rendering and therefore I didn't have decent images to show.
Second, each publication requires time to manage any resulting question and discussion and often I prefer to work silently to concentrate more on the development.

I did tons of improvements in the meantime improving graphics and speed, physics, shadows cascades, terrain elements like trees, rocks, adding a very fast instances management and improving terrain definition and 3d clouds!

Within a month I should be able to release a new video including planetary depart and flyby with mountains with trees and seamless interstellar travel to an exoplanet.

After that video every basic aspect of the engine will be ready (except for sea rendering, that will be done later on) and will not require so much to have a first playable alpha... 🙂

Thank you all guys for your patience, see you soon for the new video!
