The game “Parkour Fever” is based on rotational movement of the extension. The patient’s task is to control the character and move to higher platforms. On the left side of the screen, there is a bar depicting the extension’s position, along with a marked threshold. When the patient rotates the extension to the right and crosses the threshold, a line appears indicating the character’s jump path. When the extension rotates in the opposite direction and the indicator goes below the threshold, the character jumps. The game ends after the timer expires.
