The "evidence glow" option does not seem to work, all evidence still glows. I think that it really diminished my experience with the game. It felt like it was grabbing me by the arm, and pulling me along for the experience (which is fine if you're mostly there for that), instead of an investigative play style.
Otherwise it was good, the classical music went well with things like bodies slowly passing by in the background in the centrifuge while you're pondering over things, practical humour :)
