I like that there are multiple difficulty levels and a short cutscene at the start of the game! I'm mostly confused about what the ink color is referring to in the manual, since every time I open the notebook it seems that the ink color is black. It also took me a while to understand what it meant by "note color" (the notebook cover color). I'm also confused about the note to the left side of the room that keeps saying "Cut the green wire" on the "easy" level. It seems to have no correlation to the instructions of the notebook? Otherwise, I enjoy the puzzle-like experience of this game and the atmospheric design a lot! I believe that with some improvements made to the clarity of the instruction manual, it can be an even stronger game! :D
