I've uploaded an accessible version of the pdf file: Witasy Gamebook_Accessible_Version_Zero_Print Friendly.pdf
This accessible version already has a report attached to it, so anyone can access it. This PDF version should check the - An “accessible” electronic document is one that is optimized for screen readers and other assistive devices used by persons with disabilities. (taken from adobe).
I will be updating the main version as well but for now, it is not possible as it is still undergoing the Itchfunding, so a lot of amendments. I'll be sure to keep it updated as soon as I can.
