I also tinkered with the invincible knight idea. I would've liked that the bow shot where I was pointing to with my mouse rather than the hero's direction. Nice that you shipped!
That was one of our ideas, but we wanted the game to be entirely playable on keyboard without requiring a mouse. In retrospect, giving the player the ability to turn without moving (i.e. with the arrow keys) might have been a good idea. Thanks for the review!
