Puzzles are mostly fairly easy but pretty good fun with small "Aha" moments when you understand a more difficult clue. I played the first game in the series a while ago, so I don't quite remember, but I think this one was easier than the first.

The clues are presented in a wide variety of interesting ways, and they are relevant and make sense, which is the most important thing with this kind of game.

There's an acceptable background story, and there is some minor exploration (to find objects or look for clues) and interactions with machines other than the central game-play mechanism where you are presented with box after box that you need to open.

There were a couple of puzzles that I didn't completely get the clue, and I brute-forced some combinations. Unfortunately, once you open a box, you're ushered to the next box, and cannot review why the clues made sense for what ultimately worked if you used some brute force or just got lucky. I think I only felt that way after two puzzles.
