The Long Dark [Steam, Official Site, GOG] is a beautiful survival game from Hinterland Studio. It's a good game, but it does suffer from one really annoying and game breaking issue on Linux.
The mouse vanishes in-game, which makes it nearly impossible to play when trying to interact with the UI. Luckily, there's a quick fix you can do for now.
All you need to do is go into the main options inside the game, then go into the controls section. Find the "Lock mouse to screen" option and set it to "unlocked". This will now actually give you a proper mouse and enable you to enjoy the game.
I'm really looking forward to the final release on this one, since it will gain a full story mode. The first two episodes of the story will launch when the game leaves Early Access on August 1st. While the sandbox survival mode is fun, I'm much more interested in story games when it's single player.
The Long Dark is currently 60% off in the Steam sale, good chance to nab it while it's hot.
