난이도: 초급

In this live training session we will look at creating a multiple choice quiz game. We will create the core game loop - timer, score, win and lose states. We will also show code architecture best practices - keeping data and logic separate, and how to structure a game in a way that makes it easy to maintain and extend. We will look at some of the ways we can extend this in session two.
