The heuristics presented in this section of the chapter are general guidelines that increase the chances of designing an efficient user interface—they are not specific rules that have to be followed in all circumstances.
Performing an inspection of the game while using heuristics is a good way to evaluate its usability and identify issues the player may encounter. You can do the following:
Imagine and write down a typical player's journey through the game.
Follow the scenario, keeping those heuristics in mind, and write down every difficulty you might come across.
Discuss your findings with the design team to find solutions to fix them.
Now, let's discuss the usability criteria, starting with the notion of guidance.
