There are many ways to navigate through my App depending on where you start. Although it is recommended to begin with the yellow circle (Emergency Launch) it is not necessary, the user could start in any other and still learn the same.
Through user testing I discovered that the terminology aspect of the App had to be included within the building aspect of it, because children want to quickly get to that fun part and if all the theory is at the beginning they lose interest. This is the reason why I decided to change that and mix them together, so after the children guess each of the terms they are allowed to design that specific part of the spacecraft and once they move on to the next part they need to guess the term again.
The flow and architecture of the interface is shown in the image below
