Thanks for a great guide! I am creating a similar puzzle game. But objects are not same. One is a question, one is an answer. (question is: 15+5) answer is (20) so people should get the game object with question text on it, and drag & drop it in to answer. How would you approach that? In here, we are checking if object's are equal. But in my example, i cant do that.
