The cycle starts with the planning stage, which includes brainstorming, organizing the work (as we have seen, for instance, in Scrum), and so on. In the next phase, development, we actually create the application, as we did in the last chapter. Then, there is the playtesting, which we have seen in this chapter. In the latter stage, we tune and tweak values, as well as fix bugs in our application.

Afterwards, we iterate the whole cycle again, by entering the planning stage again. Here, we need to plan the next iteration, what should be left, what should be done better, and what to remove. All these decisions should be based on what we have collected in the playtesting stage. The cycle is well represented in the following figure as a spiral...
