About the game
Run! is a very simple game. In fact, it is the fewest number of game entities I could think of that could be considered a playable game. I designed the game around demonstrating a reusable system for game development rather than compelling gameplay. This makes the project ideal for you to add new behavior, rules, and gameplay to your own design. Or, even better, once you have learned how it works, design a completely new game of your own using the system as well as improve and add features to the system.
