Lazy Galaxy: Rebel Story from developer Coldwild Games is a squad-based shoot 'em up bullet hell that will offer full Linux support, releasing in August.
I Hate Running Backwards, a never-ending shooter developed by Binx Interactive with help from Croteam Incubator and publisher Devolver Digital should be on Linux soon.
