Love a challenge and don't get your brain in a twist easily? GRIDROAD is a fun idea putting you in charge of building roads and optimizing traffic. Imagine something like the popular Mini Metro, but quite a bit more puzzling as you deal directly with the exact flow of all the traffic.
The developer sent a key to the GamingOnLinux Steam Curator and it's been making my brain sweat a bit.
This is the first game from developer RAJACORP, and while simple it does exactly what you expect it to and the design is so clean it's great. If you love puzzle sims this is one you should take a look at and it works perfectly. Currently you'll get a couple of hours out of it but the developer has plans to expand it with a lot more levels, online leaderboards, sharing of level solutions, a custom level editor and browser, Steam features like cards and achievements and more.
Fantastic start for a puzzler.
Available in Early Access with Native Linux support on Steam.
