Yeah, I figured you checked that kinda stuff considering how tight battery was. Really it's not terrible once you get the hang of it, just camera stall Sweepin' Time by flipping it every once in a while, if he's there then great, if he's not then close the left door and just spam the camera until he goes back.
Either way, still a great demo, and I'm excited to see what you have in store for the future!
