It's been a while since I got mine set up and working, but IIRC all I had to do was install Android Auto from the preinstalled GrapheneOS App Store app
I've played Abiotic twice and have enjoyed it, but both times I've stopping before finishing it. I've been playing solo and know that playing with friends is a much better experience but sadly none of my friends want to buy it. Would you say it's worth finishing? I've gotten to third third lab area
I had a problem loading it during the playtest (black screen, forever loading icon) and had to install Proton EasyAntiCheat Runtime for it to start up properly. Never had a problem launching the playtest or full game after that!
That's the point, but it doesn't require an ISP
