@RevdKathy, thanks

In the final (game) version, we will need some 'dots', depending on controls (e.g. one for accelerometer controls, also for places where tapped). This should however be in a form of nice graphics, either semi-transparent circles or actual objects (dogs, shepherds, carrots).

Engine is ready for permanent penning, it's a matter of adding one loop. It can be dynamically adjusted, depending on level.
