I really like how you navigate through the level. The art is quite nice. I think a close button would be nice when you pick up and investigate things, or for the various screens just to make it more obvious how to exit that screen. I did find the music to be a little repetitive. I got stuck in the room with the two locked doors, could not figure out how to pry the other door open or find the keys. found the book and tried using 09 24 1975 and 24 09 1975 and could not figure out how to open the book. yup I am stuck
