In order to avoid using a keyboard to control the game, I set the starting condition for the game to 'the distance of two dots are very small'. So, you can try more to make the dots closer.
If this game still doesn't work, please feel free to comment at any time.
If you need one, I am willing to release a version with more relaxed startup conditions.
But one possible cause of the malfunction is that your computer is not connected to a camera. Please ensure that the computer can connect to the camera (laptop built-in camera or USB external camera).
