The Steam Deck has over 5,000+ verified and playable titles at the time of writing this, and for some reason Dust: An Elysian Tail is not one of them! I’ve thrown a few hours into it on my Steam Deck between now and yesterday, and I haven’t had any issues. It looks fine at native resolution – I can read everything on the screen, and it has a native Linux build. My only other guess would be that it came out in 2014, and the developers haven’t looked back at it since. Verified or not, it works and I’ve been having fun slashing my sword in the air and collecting all the Wall Chickens I can eat!
