I like the tutorial. The difficulty is a bit too high though. I would make 2 suggestions:
Show what each item and map object does without having to hover over them. For example, if you'll lose all gold on a map cell, then there should be some kind of icon indicating that (for example, a bag of gold with a red X). This way I don't have to hover over everything.
Also, there should be an undo button (if there already is one, I don't think the tutorial covered it)
