game runs very well,but only if you can bear the slow speed.turning off the audio(set to null)speeds up things a bit.played till the end,found no graphical bug whatsoever,but that only if you use Vulkan.d12 and opengl have serious glitches,and even more slow speed
UPDATE:the game has 3 graphic settings,more like graphic filters.by default is set to "crisp",but if you set it to "classic",the more pixellated one,and set the game speed to "normal"(rather than turbo)the game gains even more speed,and on stages with few details,or the training stage,the game gets 60 fps rock solid,making it basically perfectly playable
