It took me way to long to notice that you can only use TAB while in the RMB menu. I first thought you could swap characters with TAB, and was going to complain that it didn't work. Then I though the menu was broken since it didn't do anything when I unpressed RMB while hovering a command.
Anyway, not a fan of the RMB menu, having to hold RMB and scroll doesn't feel good in a game which (I at least) play completely by mouse.
The concept seems good though, I just didn't like the controls.
I wouldn't call losing an officer Masterful, kinda contrasts with the Game Over.
