Overall graphics and artwork are awesome in this game, and most of the button placement and interactions in the game are great.
One area I feel could use some tweaking is the queen action screens. I think the 2 ways to access the information are fine, but they are basically the same I think they should be merged and both look the same.
... or maybe just add a back button on the queen pop-up when viewing the description of each icon. I know you can tap anywhere and go back, but it feels like there should be a button.
