There is a lot about this game that is a mystery. The devs of the game have done and continue to do an extremely poor job explaining the game and communicating changes to players. For example, how does one get red crystals? That information is not found anywhere in the game nor on their Twitter account. My suggestion is pay attention to the level progress bar and see if it goes up after successful battles or when you complete a building, tech, or unit upgrade.
