Most of those are the screens that's not shown in the video. They aren't shown in the video because they're being re-done with new artwork. Some of them are being re-done because of some game design changes. Most of the game is functional, except for the space combat one, which just merely lets you select ships, retreat, or end turn.
Some of the screens require new artwork, such as the ground combat. I can't afford those just yet, but hopefully soon I will!
