With the snapshot, it's clear that it's just a spelling issue.
In "Game.cs" the namespace is spelled "TreehouseDefense" (with an "s"), but in all the other modules it is spelled "TreehouseDefence" (with a "c"). The choice of spelling doesn't matter, but all modules must use the same one.
Always check the compiler error messages, the one saying "Are you missing `TreehouseDefence' using directive?" was the clue that helped me spot that.
