You've got a good prototype on your hands here. Personally, I'd keep the narrative as its completely ridiculous and can then allow for more over-the-top content. Nothing says fun like planes, maces, feathers, and blood. There are all sorts of ways that you could extend this into a full game. For an hour long jam, you developed an interesting concept. Keep at it, I hope to see it in the AppStore some day :) (mobile would make the swing mechanic interesting given the use of gyros!!)
