You've now worked with basic key-bound input and Unity's built-in input axes and have made your own. Key-bound input is fine for testing and debugging, but you'll thank yourself later if you follow Unity's input pattern (or your own) rigidly.
Unity's input system in particular allows you to check several different buttons or keys with a single input name. This is helpful for avoiding long blocks of code and also allows you to add more input methods later without changing the code.
In this chapter, we started what will eventually become a full game that we build upon in every chapter from here on. It's still small and simple, but we'll add to both our player and the world around them to make it an immersive and fun experience. In the next chapter, we'll add more presence to the game by establishing an actual level environment and tools that the player can pick up and use to augment their experience.
