Maybe it's just because I've played through the full version 4 times, but I felt that the chibi artstyle detracted from some of the more emotional moments in the story. I think the artstyle could work fine if their mouths moved or eyes emoted at all, but as it is, it's tough to get fully invested in these little guys.

It's still a perfectly fine way to play the game if you want to cut out all the open world guff, but come the last third it sort of just becomes a slightly shorter, but still similar experience to the main game.
