Invitation to Participate in an Experiment Thank you for your interest in the hypothesis on the symmetry of vision and hands. This experiment measures the brain's ability to process information from vision to the brain and from the brain to the hands using a game. It also examines improvements in these abilities through repetition. The game involves controlling two separate characters with your left and right hands, aiming to reach the goal of the stage. Characters can change direction, jump, and run. While the game itself is simple, controlling two characters independently with separate hands can cause significant stress for participants. Please take breaks as needed and avoid forcing yourself to continue the experiment. === Features of the Game Used in the Experiment === * Top-down action * Frustration-inducing gameplay * Brain training
