2D Game Development Using Unity

I feel that this game is suitable for everyone who wants to study programming from scratch. I could introduce the flow of programming, binary search, or the concept of recursion through this game. It is suitable for the undergraduate and postgraduate who start to learn programming. I want to my game work like Playground in Ios platform to teach programming but I hope game will not be complex.
I want this game to be simple and run on the PC, and I hope my character could be a cat.
