Ah, but Keepsakes' excellent ingame hint system ( I think it was a little question mark) actually made a walkthrough unecessary, as it helped you with the puzzles along a graded help system, you could ask for help from level 1-5, by clicking on the little question mark.
Only with the very last puzzle, did you not get help from the game itself, so for that puzzle, you might require a walkthrough.
