This stack is free. Please give it to all your friends. However, if you modify it, please add your name and a description of your modification. This is partly so that if you break it,I'll have an excuse, and partly so that if a heavily hacked version comes back to me, I'll get to see exactly what people have done to it.
If you find this game fun, valuable, or educational, I do ask one thing: take a moment to give me some feedback on it. I've learned a lot writing Hyperquackey, but I hope I'll learn even more after getting your comments.
