Whether you're looking to demonstrate your mastery of OOP, MVC, or even AI, this game has it all!
If you've built it before, take an hour to try another approach. One-player, use a framework, play it on the commandline, realtime multiplayer (link 2, link 3), redux, etc.
Or, if you're not sure where to start, you're not alone, read how other folks worked through this project here and feel free to check out the basic-solution branch on this repo.
