Carto

Here is my 100% Achievement guide and actual full walkthrough!
Originally, this achievement seemed to be buggy but a lot of reports have suggested you don't need to sit through this in one sitting, can come back to it anytime and this particular achievement will still unlock.

Otherwise, its an enjoyable game, timestamps for all levels and achievements will be below the video incase you need them for any particular part.

Hope the guide helps!
Enjoy :)

In order to do this you have to clear the game + the 6 puzzle pieces +the 2 extra achievements ( the books and the Hanoi tower ).

The bug that prevents the achievement to pop for a lot of people works like this:

When you exit the game you lose all your progress with the exception of saved games. What does that mean towards the achievement : if you had finished the game with all 6 puzzle pieces enter that save game and finish it again ( you now have the clearing the game + 6 puzzle pieces ); you still have the hanoi tower ( chapter 8-1) and the books, but for the books you will have to return to every chapter that includes the Chalet and read all the books plus Carto's book ( sometimes Carto's book must be read multiple times as it changes before and after the task in hand ).

So it isn't required to finish it in one sitting in theory, but i recommend that you do it without exiting the game. Took me around 2 hours.

A full and fast achievements guide in the video.

This doesn't need to be completed on one save file. Using chapter select will unlock it once all other achievements are earned.

Edit: This may require being completed in one sitting without exiting the game.

As noted in the comments, the Hanoi puzzle completion is also required, if you're missing something try the puzzle again.
