I am glad you enjoy the game!
1) Blue Jazz attacks from a distance. He does not have to be on the same space as someone to attack them. And the further away he is the higher his ATK is.
2) Hat-Nip can move two of the tiles by swapping their position with one another. But it cannot break the dungeon into two sections. So the two tiles have to be on the outer edge of the map.
3) Yes
4) you can only use food items at the start of your turn
5) it is truly up to whoever is playing as long as everyone does the same thing. We like to hide all our items and flip at the same time, that way no one knows who is using what.
Thanks for playing!
