I feel like each character should have a unique feature for themselves. Here's some ideas I came up with
Keiths trip wire and police tape: this would prevdnt the player from opening doors and would cause cause to trip over the wire
Gerdas powerful weapon: maybe imbir could go around the house and alert gerda of your whereabouts. And he would stop after you give him the treat.
Mayor:they could use the mayor's security system in the files.
Ted: security cameras but there's a limit on how many he can place.
I haven't figured out any for otto yet.
