Re: airlift, your 2-player game is using a 3D map. Each layer connects to the one above/below it. On my to do list is a guide to the available maps to detail the special features of each.
"After that, it got hung up when I clicked on the third hexagon of five armies."
When choosing actions, the pattern is first area selected starts the action, second area receives the action such as an attack or transfer. Clicking a third area does nothing. You would need to click the first or second area again to deselect.
"Also, it would be nice to have a way to cancel what you were doing, let's say, you decide not to change anything. If I click the back button, it takes me out of the game."
From the How To Play guide. "Use the No Action button to undo all of the actions in the selected map area. This must be used change the actions that have already been input." The No Action button is atop the Actions list. You should not use the Back button as it may cause the game board to hang.
