I was pointed towards Mantis Burn Racing as the developers are considering a Linux port of their fantastic looking top-down racer. They may do it with enough requests.
HEVN was pointed out by GOL follower micha and after taking a look I was impressed, so I spoke to the developer about their Linux plans for this first-person sci-fi adventure game.
I finally set aside some time to play the supernatural thriller Oxenfree and it's surprisingly good. It's a narrative-driven game, so each choice you make changes the conversations and the flow of the game.
Guns N' Boxes a game that promised a Linux version during the Greenlight campaign is now looking to put it out after many months waiting. They've asked for willing testers to help out.
The Swindle has a beta Linux client! Even better, it appears to have been well tested since its initial launch back in August 2015 and the most recent feedback is all extremely positive. Here's a short review!
Space Jammers, a game I covered before after being impressed by the early free demo is has continued development and has now had a rather quiet Steam release. UPDATED
I keep a keen eye on 'MewnBase' as it's a cute and simple survival game about a space cat trying to survive on a barren planet. It's had a few big updates recently to know about.
I've spent a bit of time flailing about in VThree, a new Early Access run and jump game based on speed-running to the end of a level. It's fun, but difficult.
'Disturbed' is a free visual adventure that was released some months ago, which got a lot of favorable reviews from Steam users. Because of this, the single developer behind the game announced, only a few weeks after its release, that there would be a sequel. And now the Steam Greenlight page is finally live.
