Have done this in #315

Would love to know if you have added something extra which I missed.

Skimmed through your PR, and here are some differences I noticed:

This one's

1.	Handling n number of users in a room.
2.	Support for both video and audio.
3.	Worker management: workers run on CPU cores and handle multiple routers, 
created initially based on CPU cores, and typically shouldn’t be one per user.
4.	Design differences.

Let me know your thoughts!

1. Since two players would be playing the game, only they need to connect over a video call, adding extra users is not needed atm.

2. Yes, I have to add audio as well, it skipped my mind

3. Will read about it more.

4. Due to implementation differences, yeah!
