This keeps happening to me, I keep writing about something and a day later it's here! Hollow Knight [Official Site] now has a Linux beta build available on Steam.
You need to select "beta-linux-" from the Betas list on the properties of the game to access it. Fantastic to see it arrive on Linux! Read more in their announcement.
The game has some of the best visuals for a 2D action game around, so I look forward to playing it when it's officially released.
About the game
Beneath the fading town of Dirtmouth sleeps an ancient, ruined kingdom. Many are drawn below the surface, searching for riches, or glory, or answers to old secrets.
Hollow Knight is a classically styled 2D action adventure across a vast interconnected world. Explore twisting caverns, ancient cities and deadly wastes; battle tainted creatures and befriend bizarre bugs; and solve ancient mysteries at the kingdom's heart.
