Thoroughly enjoyed this game. Notes made it simple although I also kept a list of "to-do" items to refer back to (there are a LOT of items to work with). Really well implemented.
Only warning is to specifically look at EVERYTHING. Missed a number of clues because I didn't specifically say to search the mantle, assuming if there was something on it the game would mention it when I looked at the area. Was a game changer when I realized my error and found much-needed clues.
Happy there was a walkthrough available just to verify a few points. Only needed actual help on one item where I wasn't using the words the game was looking for to put two things together.
I definitely enjoy this type of game more than dialogue-based games or games where you simply have to find random items and remember where they might fit. Great game!
