i have some questions
- what kind of game are you trying to make
- What is the name of your books / what are they about .
if its interactive fiction for example a text adventure or visual novel then theirs html and python that you could work with to create your game! if its a more complex game you may want to use a game engine like unity or godot engine.
It is based on the Episodes I have been publishing here, The Strays I want them to have the feel of Tell Tale Games...
Interactive fiction right you will want to check out renpy: https://www.renpy.org/ i think it can be run on android but im not sure about ipad though also sorry for the late reply.
Oh no worries at all! Thank you so much for your advice!
