I’m currently working hard on something to fill this void! I’ve made HomeHook v2 as a web app and HomeCast as an mpv interface installed on my HTPC and some Pis I have around the house!
I still need to document the installation procedure but if you’re interested in playing stuff from Jellyfin and YouTube, feel free to send me a message and I’ll see if I can help out!
I managed to get the game’s textures working well through Lutris with this script I found!

It’ll compile and install latest mesa, just make sure you add the wrapper script to the command in the lutris config for the launcher and it should work great.
Managed to make it work first try with this script on my KDE plasma/debian testing setup after wrestling with the textures issue for several days.
