The game is pretty much Grand Theft Auto in 1940. I love the music and the dialogue is better than I expected. Finding clues will be tricky if you don't use the help & tips but I suppose it makes the game interesting.
Played it more today, I'm on the second case of Traffic cop and enjoying it so far. The whole of the Beat cop route is pretty much tutorials, after that you're on your own. I've only used intuition once so far and it was in interrogation, it just removes one response you can use. Not used one on a crime scene because where is the fun on having all clues revealed?
