I really love the visual treatment--both the hand drawn graphics as well as the paper stack effect. Definitely nailed the theme on this one :)
The limb controls reminded me of QWOP. Fun and frustrating at the same time. Maybe a smaller/easier battle could be added near the beginning before getting swarmed by enemies and arrows in order to get people used to the mechanics? Once I figured out how it was supposed to work, though, flailing at my enemies was quite enjoyable, even when the odds seemed stacked against me.
