Excerpt from the Interview:
5: Can you describe to me a little about how the game plays, controls, the story?
"The game is a platformer with action and puzzle solving elements. You'll run through levels collecting clues and fighting monsters and henchmen along the way. Eventually, about half way through each mystery, you will enter a chase sequence where that mystery's villain chases you through a level and you have to run away. At the end of each mystery there is a boss fight where you fight the villain from that episode and try to guess who is behind the crime before you unmask them.
There is a lot of content to unlock along the way, such as new character costumes (each with their own abilities) and trophies for accomplishing certain tasks."
