The new update (0.21) is a complete left turn. The wrap up of the extremely short summer vacation (the literal title of the game) came out of nowhere leaving more questions than answers and, overall, made absolutely no sense. Pretty clear that the dev lost interest in the original story and ham-fisted a way to drop it and start on a new and completely different story - Mat, the College Years. Unfortunate.

Yeah, I have to agree. Such a 180, without resolving any of the tension (you'd think there'd be at least one scene with the uncle, if that's the way you were leaning) or actually finishing out the summer. It was really disappointing. Hopefully the college story will pick up soon and the uncle will come back into the picture. Wouldn't mind if Carlos stayed gone though.
