Brain Age speedrun (!) by Ryuto. Instead of correctly answering the problems in this tool-assisted speedrun, Ryuto draws images that incorporate the strokes that the game uses to recognize numbers.
The result is a high-speed, kind of psychotic flash of weird patterns, random drawings, and Super Smash Bros. fanart. 6 x 5 = Maxim Tomato? The “speedrun” could have been done more quickly, but “the run aims to be as entertaining as possible.”
