there already exists a flatpak, hell even i have it installed, i havent heard about it being published anywhere (afaik it will be „official” when v2 fully releases) tho. I can send it to you if you want

Here it is https://github.com/Vulcalien/uk.betacraft.BetaCraft

thx to the awesome work of @full nexus

I'll make a flatpak and an AUR package after the core c++ rewrite

sadly flatpak-builder doesn't come with Steam OS
