Really excellent. Given few resources you've crafted a little world with a lot of character - I particularly laughed at the shopkeeper's line. The crowds with their various shoutings were great and the action gameplay was blisteringly colourful and well paced.
The only error I could see was that mashing any/all arrow keys worked just as well as trying to hit the correct one - which made it hard to resist once figured out. Really great work, one of the best I've come accross :D
