I'm really fed up with people barging in, copying and pasting a bunch of connection numbers in the chat without saying anything else (hello?), and then disconnecting right away. So, while I'm still working on getting ZGameEditor to work for Android 64-bit, I took a look at what can be done with the peerjs library to handle some kind of lobby.

I found this: https://github.com/Glidias/peerjs-lobby
I'll investigate when I'll have some time.

Edit:
Careful, that github was updated 11 years ago... 🫤
