Hello :wave,
I am considering buying the book, but before I do it, I have the following question:
I have noticed that periodically you update the content of the book (based on readers' feedback, new ideas which pop up in your mind, when it comes to what in your opinion would be useful for people to know etc.). Do I need to pay 20$ (+ VAT etc.) for every new version that gets published? Should the answer to the previous question be "No, you do not have to pay additional money" - then how do I get access to the latest up to date version of the book (in the "Development log" section of this web page)?
I've never used itch.io before, which is why I am unfamiliar with how things work.
P.S. - considering all the positive feedback you are receiving - it feels like you'd benefit significantly from promoting your content more actively :) I only found the book by pure luck.
Kind regards,
