Blue Prince is a great game. It's basically a roguelite puzzle game, where you build out the rooms of the Mt Holly Mansion. Early on, the game tells you to take notes, as there are many details for puzzles in the game which you solve throughout your time playing. I took this to heart, using my personal notebook to keep notes on paper. I have 28 pages of notes about the game. It ignites the same sense of discovery that Outer Wilds (one of my favorite games of all time) provides. It's very impressive for a game to recreate that experience, and avoiding spoilers for Blue Prince is by far the best way to experience the game. That said, spoilers are kind of hard to get for it. Instead, puzzle solution spoilers are the biggest thing to avoid, as it is far less fun to not figure things out yourself.
