Hi there, just a simple suggestion. Add a custom mouse cursor. Any, it doesn't matter which one. It's to avoid breaking the inmersion of still being on a Windows App instead of a game.
Many games fail to realise this, and don't use one. And this game always tell you "Clic to X", so the mouse is used quite often if you want to.

Also, a very very minor thing, the Help Menu "?", is missing a "And you pass a turn!" ( http://puu.sh/mX63c/980cca1b6b.jpg ) on the swap button.
