For just today the game store itch.io is running another Creator Day where they don't take a cut from any sales. Their store should also work fine on the Steam Deck.
Even though creators on itch can manually set what revenue cut they give itch, which could even be zero, itch will give 100% to all creators until 7 AM UTC Saturday, July 24. So this might be a good time to hit that purchase button on some fun indies you might have been holding back on, or actually donate to those that give their stuff away for free.
Need suggestions? Well, we have our own list (a bit like our Steam Curator) of some of the best Linux games available on itch. There's around 100 on our list now so it's growing nicely and an easy way for us to show you what we recommend.
Interestingly, itch owner Leaf Corcoran mentioned on Twitter how the itch store application (which is open source) "should run perfectly fine on a stock Steam Deck, no OS changes needed" and that he does "actually develop on Arch Linux system so I can confirm the app works well and is easy to install".
In a follow-up Twitter post, Corcoran mentions that the itch client does also hook up with Wine so that Windows-only games might work on Linux / SteamOS but it's nowhere near as integrated as Proton is with the Steam client and itch doesn't support it directly either. Pretty great though, hopefully it means the Steam Deck with itch on the desktop mode could turn into an even bigger and more fun device.
