This was an awesome idea! I loved the premise, art, and resource management aspect of the game. It is certainly difficult, but I won't hold that against it. For the quick time build requests, I think having some text accompanying the image (like "We need a barracks" or something) will help further communicate to the player what build is needed for the extra reward. I only mention this because I found it a little confusing which build I was meant to make. Otherwise, I really enjoyed playing!
