How to test multiplayer

Hi @LabyStudio
Thank you so much for this awesome project
When I press the demo and enter multiplayer, nothing happens
https://labystudio.de/page/minecraft/
Could you please help me how set up and test that function?
Thank you!

Refactoring this app

Hi, I like this project a lot. The main issue with why the app is so laggy is that you literally added whole libraries to this app. I think the better approach would be to use npm to install all these libraries and then use a module bundler like webpack or rollup.

I can help you with that if you're interested :D

Super laggy

Dunno if its just me but its super laggy and kind of unplayable

Multiplayer

@LabyStudio how do i setup a server?
I would love to carry on this project but this is a major block

License is missing

Hi, nice work!
Does this project is open source?
If so, can you provide License?
I'd like to refactoring this project in Typescript and other modern setup of javascript .
