Aaaaaa, I found all the evidence, and asked around but I still could not put it together... The music is lovely, and I love the art. Poor Aunt Susan... Bear is adorable, and I LOVE Grandpa...
Hmm, so he was early at the beach, Tony dropped a recorder in poop, Barney ripped his shirt somewhere and said he had to use the restroom... And he doesn't seem the drinker type, so someone is clearly lying... The twins definitely stole the cards, and....gah. I can't think beyond that... I'm bad at this.
Regardless, amazing game! Polish is off the charts, the sfx and ambience is well done.
