Revised and improved mockup: Added green circles and dots to simulate player selecting unit and moving it (the circles may also designate a target to move to). The train button darkens to simulate a click. And there is now a main menu in the demo that simulates a player saving and resuming the game. The end where the enemy concedes was mainly just to shorten the demo, though it is not a bad idea to implement in the real game.

The mockup still runs a little fast, as if an expert player is playing it. However, it is a lot slower than it originally was (I almost halved the frame-rate to slow it down from the original, because you had to watch it a few times to catch everything going on).
