I beat Thimbleweed Park last night. It requires two play-throughs to 100% achievements.
Overall it's an excellent P&C Adventure game. There are a few places it stumbles but I'm not actually sure if it was *intended* to be "bad" in those particular instances. Without giving out spoilers, I'll give an example that was used in-game.
Very early on in the game, there is a moment where the fourth wall is broken and they reassure the player that Thimbleweed Park is not like Sierra games where the game can suddenly end and you'll need to back track through saves. But there actually *is* one instance where, KABOOM, game over, you shouldn't have done that, reload.
We, the players, are given fourth-wall-breaking information that is purposely false. While at first I thought this was just tongue-in-cheek stuff to laugh at older P&C tropes, instead I'm now thinking that there is an added layer of mystery that we're supposed to figure out?
The first half of the game starts with a Mystery Murder whose protagonists have hidden agendas themselves. During the course of the game as you reveal the plot, I almost feel like the mystery inverts itself. Like the information that we're given as players is, once again, false.
That is to say, I think there are multiple endings, but I've only experienced one. I experienced the one where I thought the fourth wall breaking information was truthful.
Naturally I could be WELL over-thinking things, but having experienced an ending that was kind of lackluster and re-thinking events that happened in the game, I have to wonder if there aren't more layers.
Anyhoo, Thimbleweed Park is solid even if you take everything at face value in the game.
Side-note: the voice actor for Leisure Suit Larry uses the Larry voice in the game. Not sure why that is either. MORE MYSTERIES.
