*4.1. Goals*

The user evaluation aimed to see how patients with T1D experience the game, a core element of gaming [57]. We used a mixed methods approach (i.e., direct observation, questionnaires, and semi structured interviews) to answer the following questions: Do players like to step into the "magic circle" [58] and does striving for progress in the game motivate healthy behaviours? Do users appreciate the coaching messages? Do users find the educational films useful? Do users find it difficult to use the system? Do users encounter any technical problems they cannot solve?
