I just completed drag and drop of the in-game cards on mobile devices. I hope to make the mobile device look more like...a secret agent mobile device...but for now it shows a briefcase to have at least some flavor. Players can now connect to the game by scanning a QR code off the TV and then arrange their cards by touch. Multitouch also works--I'm not sure if you'd want to move multiple cards at the same time, but it does work. Selecting a card pops it in the z-order.
Not only is this "game" not fun yet, it isn't even a game. I plan to make some minimal card game (basically, "War" or "Go Fish" equivalent) and then expand it more towards the rules I have planned.
My current design is to much more abstract than I originally envisioned. Instead of seeing a map of the game, a series of encounters will arise Munchkin-style and the players will resolve them. The encounters will follow a trajectory based on the mission theme instead of being random.
