Hey Brian,
First off, I want to say that I am very impressed with the AI in this game. Not only do their decisions actually make sense, but they're smooth and seamless and clearly get the message across what they're actually doing. The little animations that are spread throughout the game are not only adorable, but a great polishing touch on your game.
I don't really have much to say improvements wise, but I think that the main thing I'd say is adding a new font. The default Unity font is a bit bland and I'm sure a nice medieval font would make it look that much better. Another thing would be having the heal move heal the player a little bit more. Maybe by another 10% or so. Other than that, excellent job Brian! Your game was very fun to play, despite myself not ever playing any games in this genre.
