Some more thoughts as I play more...add a restart option when game over. It happens a lot, lol, so easier than resetting the cart.
Is there any "herding" logic build in? I can't tell...but would be nifty if as you walked around (and your dog) it would push the sheep towards the middle or something. Something that makes it feel like I have a little more control over those sheep banging into the edges. The stealer guys are rough! Or maybe save the stealer guys for a later level...start off with the green gobblers?
Also took me a bit to realize the wizard can't get hurt by the baddies and my sheep can't get shot by me.
