The AI is rough. I can beat it at medium now and again, but at the higher levels... oooph. :-)
We weren't quite sure whether the bigger pieces would add to or subtract from the game. But it's interesting to try out, no ? I actually do feel they give an interesting twist, as they add an extra choice to consider, and bring pros and cons with them.
Anyway, thanks for giving oyr game a chance. And sooo glad you enjoyed the atmosphere we went for!
