Back in the day, there were lots of websites where you could play the game. You can improve your performance at this game by playing in extremely high contrast, so you can use the retinal afterimage to give you more time to study the numbers. Similar to how that "LSD" video requires you reconstruct persistence of visionsl while watching a too-slow animation of light painting. Such a weird case, since any human could directly objectively test the claim on their own. https://www.novelgames.com/en/ayumu/ https://www.novelgames.com/en/ayumu/
