I spent most of yesterday fiddling around with lots of different control methods for the Sheep Herding game.
After a number of methods, I've settled on having "Come" and "Go" buttons.

-=-=-

Push one, and the sheepdog comes towards you.
Push the other, and the sheepdog goes away.
With those two buttons and the sheep constantly running from the sheepdog, there's a vaguely controllable game appearing from the chaos.

Next I need to add some kind of fencing method that will allow for "tracks" that you need to guide the sheep through.
I'm also wondering if I need to add any sort of dangers along the way, but that will probably become obvious as I make more of the gameplay work in the engine.

I also need to animate the characters a little. They're currently rather static sprites. I might also make them a little larger, onscreen, too. Although that depends on how the tracks look when I add them into the mix.

Plenty to do!!
