I managed to do it online multiplayer. Though as my fears were it is too laggy to play smoothly. I did it quite the way the tutorial was showing, so simulation is happening on the host game. players send an input, it is simulated on host and then it is given position and rotation back to the peer, and the latency of input is too slow to make it playable. but i am working on a different idea of this. we will see. i will upload the new version i guess today.
