Over many weeks, the story developed with a series of play
tests with small groups of children, who noted in actions and
words which story elements worked and which were still
confusing. The last of the project's play tests (see next section)
confrrmed that the implemented story was presented clearly,
understood, and helped drive the player to success for grades
K-3 across boys and girls. Fig. 3 illustrates some of the steps
of the game with screen shots.
