Hi, thanks for this game, but I was unable to try it cause of that Vulkan requirement.
As a Linux user I hope you'll try building games with also OpenGL support in the future since, up to now, Vulkan is still available on most recent GPU only, while older (and not so older) hardware still relay on OpenGL.
Correct me if I'm wrong, but I think UE4 currently support Linux build with Vulkan only: if that's so why don't using Unity3D engine instead that still support OpenGL Linux builds?
Thanks for your time.
