That's close to where I was planning to go with it. I was considering adding some NPC's that you could interact with and do various things for. Something like the quartermaster needs new archer recruits, get a certain amount of points by shooting an archery target. Multiplayer also crossed my mind for a short time.
I'm certainly open to suggestions! This was my first "launched" game and I mainly did it to showcase what I knew for VR development.
