I thing i know why my laptop doesn't support vulkan and only able to support dx11 , so unless the dev makes the dx 11 version us potato pc players are screwed
If your pc can't play either version you could try running the game from the command line using the following command: HardStuck.exe --rendering-driver opengl3
The opengl mode has a lot of issues with lighting and color but the game should be playable even on older hardware.
