I used the method provided by Indesign & Acrobat to convert a project into an accessible version. I would say it wasn't too difficult but, the part for the alt text took me quite long.
After that, the tagging in InDesign and full check-in acrobat was a breeze. Provided the style's within my document are already properly assigned.
Thanks for giving game creator like me this awareness :D
Also, quite an amazing learning experience to prepare for this. I'm not sure about an audio version though. I might be doing that next, but my game has a lot of tables, does anyone have any examples?
