This game is absolutely fantastic. All of the evidence-gathering puzzles are solvable without needing any hints (another poster said the date puzzle was not solvable, but it most definitely was) but hints are available if you do need them. My only gripe was the ending... It wasn't clear to me when/how I was "done." Plus, I was carrying something I should not have taken, but the game would not let me drop it and then leave the room. Unfortunately I had not saved early enough and was stuck with the one ending. However, even with this disappointment, I still give the game 5 stars! I highly recommend it.
