Pretty fun! If you made it so that the eyes were Punnett Squares it would even be a good way for students to understand how it works in the traditional sense they'll see in textbooks. I actually learned about blood types through this so that was really nice.
But, I can't sympathize/work for with the secret organization because they hadn't given me a good reason to really split up a child from their biological mother and father.
I'd like to see a more fleshed out version of this game where the parents are more varied.
