Hi from desktop mode!

I use a Arch Linux install (configured to have a ‘as close as possible to SteamOS 3’ experience, so I still have the usual gaming mode and desktop mode) and I use desktop mode for web browsing, programming (and related stuff), system maintenance and installing stuff.

I use Gaming Mode for gaming, ofc.

No problem.

Downpour has Jolly coop integrated

I’m playing Rain World now, the dlc has up to 4 player coop

Rain World, gotta 100% the game.
