Maybe I’m not so creative as other forum members, and I have not write any gamebook text yet, but I have created mobile versions of them. Mostly I have created mobile gamebooks with Polish text such as “Afrykański Świt”, Tajemne Oblicze Świata" etc… But you may be interested in one in English. This was developed by me for other company: https://play.google.com/store/apps/details?id=com.jwa.lost&hl=pl This is a paid app, so be careful ;). I’m not getting any money from it, just saying. Maybe someone will be interested in this game.
