The game is called Subpixel Snake and can technically played if you put all of your settings to maximum zoom and hold a magnifying glass up to your screen, but even then you would have a tough time of actually building a long snake or seeing anything that’s going on. You can check it out in action and learn more about subpixels in Patrick’s Video below, and you can also have a go at the game on his website. I’ve tried making this work on my Mac and I can’t get anywhere near close enough to see what’s going on, but if you do have a microscope handy or can put your Mac on the other end of the Hubble telescope, then you might stand a chance!
