【Not just a game, but an experiment in evolution】 Inspired by the famous "Ayumu Project" at Kyoto University. A chimpanzee named Ayumu demonstrated an eidetic memory capability that leaves most humans in the dust. It makes us wonder: along the millions of years of evolution, as we gained language and logic, did we lose some primal, powerful instincts? This app brings that legendary laboratory challenge to your phone. 【The Core Challenge】 Numbers flash on the screen and vanish in the blink of an eye. You must tap them in the correct order relying solely on your instantaneous visual afterimage. Eidetic (0.5s): Think like Ayumu. Challenge the limits of humanity. Average (2.0s): A starting point for most sapiens. Rote (10.0s): Take your time. For those who admit defeat (jk). 【Ultimate Experience】 To replicate the purest reaction test, we've optimized this app to the millisecond: Zero-Latency Audio: Built with iOS SystemSound API for instant feedback the moment you touch. Fluid Interaction: No superfluous animations to drag down your reaction speed. Minimalist Aesthetic: High-contrast black and white design to keep you hyper-focused. 【Secret Features】 Too hard or too easy? Try a LONG PRESS on the start button. Want to know the story? Try SHAKING your phone. This might be the simplest game on your phone, yet the hardest challenge you'll ever face. Can you reclaim your primal power?
