Who stole the cookie from the cookie jar?

I don't really know when or how I got the idea, but suddenly I had a prototype of a game in front of me. It was a remake of a game I love called LoverLetter. My game is about Icelandic Christmas cakes and cookies and the goal is to find the cookie thief. Here is my prototype that I have been carrying around to make my friends try and brainstorm with me.
