Can the developer please point out the reasons why exactly this game requires Vulkan support? From what I’ve seen, not only it’s a 2D game, but there’s close to no animations other than a slideshow between different images as “frames”. I do not see a single part of this game that can truly benefit from a desktop-exclusive advanced 3D graphics rendering provided by Vulkan.
Unless there actually is a valid reason for it, please provide OpenGL builds as well so to not restrict this game to only select modern hardware. Again, there is no reason on the surface to use advanced 3D graphics for rendering game assets that look like simple images.
