We worked with 63 young people aged 11 – 19 from 3 schools to support them to create an interactive, illustrated gamebook for tablet and smartphone. Young people took part in plotting, writing, illustrating, app design and coding workshops. We had a diverse group of participants, so the workshops were targeted to their individual interests, aptitudes, abilities and educational needs. Young people worked with professional writers, illustrators, musicians and developers. The final game book is available on the iOS App Store and Google Play.
