Yes, I'm using PS3 controller. Don't let your controller die though if using Bluetooth, as reconnecting doesn't seem to get picked up in-game and you have to restart.
Not interested in installing Gentoo just to play a game with a controller. If I was going to use a linux distro it'd KDE Neon, Ubuntu, CentOS, or straight Debian.
I'm actually having an issue with this. I'm using a wired nintendo switch controller on Arch Linux. This controller works for other game platforms, such as retro arch, but doesn't work for this game. The game itself is beautiful and worth it to play even without the controller
