WWI Flying Circus -- What did not work well

World War I Flying Circus (WWIFC) is a turn-based WWI biplane dogfight game. It's like playing chess in the air, but with one difference -- white and black move at the same time.

This video highlights what did not work well during my heads-down development months. I have had problems with Unity Technologies (an Integrated Development Environment, or IDE) integration of some of the high-complexity and high-value packages such as Unity Ads, Unity Monetization, and Unity In-App Purchasing. Most likely my own "pilot error" but these problems have consumed a lot of my time.
