Hah, one of the doorbells in the town was misaligned! You have to examine to the left of this door for the doorbell sound to ring while all others you examine the door itself. Literally unplayable.
I didn't realize until now, but the one house you can enter has Dream Aubrey's version of Lost At A Sleepover playing in the background. Just slowed down like the other outside songs. That's neat.
