  33. Fidelity • Hiding • How much cover is the fern...as opposed to the closet or under the table? • Do AIs perceive others and plan around them? • Do they track the babysitter? • What if they can turn on and off lights?

  34. Scale • Did your design scale when player character changed? • Does it scale when the aesthetic itself changes? • Is it still fun • To desgin • To play
