// Remarks:
// 1. Of course this is a bit limited and we will soon learn more helpful things, such as loops,
//    such that our world does not need to collapse at every misstep. But hey, it's a first game!
// 2. This might look ridiculous to you. Too simple, if you know the concept of if and else. Too bloated.
//    But there's a reason I spent a few hours of my time creating this dungeon example for you: I believe it can teach you important skills:
//     * There are programs working similar like this. Guiding a user through a website can be the same concept, for example.
//       There is a lot of spaghetti code out there.
//     * The steps from thinking about a dungeon and deciding which decisions the user has and getting the map right is an
//       important conceptual step. Try it yourself! (ok, you can maybe skip the nice story if you don't feel like it)
//     * You need to start somewhere. We could go from here and extend it step by step into something like https://writtenrealms.com/.
