Hey thanks for letting me know.
I uploaded another version of the game - if you download practiceRoundOpenGL, it should use something other than Vulkan. It won't look like the vulkan one unfortunately but hopefully it'll work for you.
If your video card or cpu is very old, it would not support certain vulkan versions which is why you're getting the error. I would keep the window on the game fairly small, there is no graphics scaling available for this version so it'll be much more intensive on your computer if you make the window too large.
You can also try updating your driver following steps like this: https://support.microsoft.com/en-us/windows/update-drivers-manually-in-windows-e...
Let me know if you have any other questions.
