From the campaign:
I can’t believe that we’re actually chasing the Air Chess Set down, there isn’t much further to go until the third set is done and then I can get started on the multiplayer rules and we can look at putting in some cool dice. Then it’s all about the Ice Chess Set.
Not only have we got the first two chess sets funded, but you've allowed us to be able to produce the scenery and the Rulebook. You can see more about my vision in this gameplay video or by downloading the free Sample Rules PDF!
