Easily one of my top 10 favourite Linux games released last year, Dead Cells, is about to get a huge free update. There's also a sweet mini documentary about the developer.
Aeon of Sands - The Trail is certainly attention-grabbing, with the retro look inspired by old dungeon crawlers mixed with some interesting story-telling where you create your own adventure.
After a successful Kickstarter back in 2016, LUNA The Shadow Dust development has been coming along nicely. However, a Linux version back then was only a "very high" possibility but it's now confirmed.
Heroes Ravage sadly failed the first time around on Kickstarter, it's back and this time they're going the single-player route with their rather unique idea.
A DLC release that I missed from earlier this month, one I'm sad I missed because it's great! Monster Prom: Second Term is exactly what Monster Prom needed.
ZED from indie developer Eagre Games and publisher Cyan Ventures (the new publishing arm of Myst creator Cyan) has a fresh trailer up and it does look good.
