Caïssa Board was released the 1st July 2021, at the time it was made with Unity Engine. Since then I have moved it to Unreal Engine and have brought major changes to it.
In this release I have focused on the User Interface and the Multiplayer Mode. You can now host games online and even launch a dedicated server built for Windows or Linux!
User Interface

The User Interface needed some work, so I went and redesigned most of it. The menus are now easier to understand.
Multiplayer

As I was ahead of my schedule, I've spent a couple weeks to see if I could make Linux and the multiplayer mode work. After much struggle I could finally succeed with both! This version is very basic, you can pick a side, choose a chess variant and start a game. The bells and whistles will come later.
While the dedicated servers are ready on my side, there is an issue with Steam which makes them unavailable right now. I'm working with them to fix it and in the meantime you can still host multiplayer games from your computer.

Linux
I have successfully packaged Caïssa Board for Linux! What's left to do are minor details such as installing the right chess engines. The dedicated server works already for Linux and will be available as soon as Steam unlocks it.
Bugs
Unfortunately, in order to make the multiplayer work, I had to break about everything in the game. While I have fixed the most obvious errors, you might see the game crashing on less used features. Don't hesitate to tell me if you experience any bug or crash.
Future
Before going further with the multiplayer mode, I want to stabilize the single player mode a bit more. Once done I can work on the Linux version and then expand the multiplayer mode.
