Very cool game! Reminds me a tiny bit of a turn based startegy game "Hero Academy," which also greatly limited your actions per turn. I would love to see this fleshed out with sounds and some more missions! It was very satisfying once I learned how to fight enemies. I think you have just the right amount of depth here.
The game did lock up on me when i tried to capture the castle in the southeast. A little sad, but i still had fun. Well done!
