The puzzles could have been more challenging.
Yes. I was waiting for a "
Le Serpent Rouge" or "
Lewis Carroll Scavenger Hunt" type of puzzle that never came. "Moebius" never gave us a compelling or fascinating puzzle that kept us awake at night pondering. Everything was just a standard kind of puzzle, that took no consideration to solve.
You may tout the character/artifact analysis puzzles as "new and different" and there is some merit to this notion. But the crux of the game--the "moebius theory" of repeated lives--puzzles could each be solved within 30 seconds once the player realises the pattern of the puzzle ( which is a simple process of elimination). All of the text describing the historical figures is a smokescreen because the mechanics of the puzzle only requires a visual observation of the photos/paintings. It's an interesting idea, but the execution falls completely flat.
Ultimately, the puzzles are all flat and unremarkable things. They are staples of adventure gaming but they never rise above that level of mediocrity.
Likewise the evaluation of NPCs is equally simplistic. One you understand Rector's motivation, all you have to do is choose the snarkiest description to get the correct answer within seconds.
And the maze (which serves as a third act???) is the easiest maze I've ever encountered in an adventure game. It was impossible to get lost, even if you ignored the obvious markers.
