I like the concept of the game, it's really unique! I don't think it fits the theme very well, though. The game is fun, but I think it could use some general tweaks. For example, It would feel a lot better if, instead of having to click on the tile underneath an enemy to attack him, you could just click the enemy himself. Also, I wish there was a indicator to tell you how many moves you can make.
Overall, good job!
