Great fun game if you are lucky to get it for free. It is then ad free and comes with both fast travel and hints for free too. Some items require a bit of outside the box thinking/guessing, but don't skip ahead by just guessing/brute forcing the challenges as the photos or clues will remain unused and you want know which clue belongs to it before the game ends. Sometimes it's hard to know what is a puzzle to crack and what comes with a clue. Works offline and fun to replay every few years.
