My Design for a shop interface. 4 rows, nicely sprited, that contain all the items you can buy at that shop. It would open it when they press on a specific button in the shop. They could be immune to attacks while shopping? You could also have an indicator warning them that they were being attacked. I'm not sure about that. This is just a nice design for it. :) b to go back if you change your mind about buying something.
