Before, moving on, I just want to point out a technical term about UIs, since it also appears in the official documentation of Unity. Some UIs are not fixed on the screen, but actually, have a physical space within the game environment. In saying this, there are four types of interfaces are diegetic, non-diegetic, meta, and spatial. Each of these has its own specific use and effect when it comes to the player's experience and some are implicit (for example, static graphics) while others are explicit (blood and dirt on the screen). However, these types can be intermixed to create some interesting interfaces and player experiences. For Angel Cakes, we will implement a simple non-diegetic UI, which will show all of the information the player needs to play the game.
