It contains 20 levels which should be played in order:
1-3: Ground floor

Every level gives you hints about a character and you have to guess who is he. After that you should scan his picture, on the museum wall, to win points.
You can ask for more hints or skip a level if you got stuck.
After winning a level you can read all the information about the guessed character.
