Update:
There was a bug with the car multiplayer test.
Sometimes the car's rotation flipped in the other player's view.
We have fixed the bug, and now it is working fine.
You can download the updated version here:

We are now working on a room feature that will allow the player to create or join a room in the game.
After that, we will add support for multiplayer private servers and create a multiplayer server installation.
We will keep you updated.

Cyberix3D team
