if you design with accessibility in mind
putting the information how accessible a game is for the visual impaired in screenshot form only, kinda defeats the purpose. So those games that are bound to have a good description to begin with, at least I would hope so
;-)
I stand by my opinion. Screenshots are the alt-picture of the description of a game. A "correct" alt-text for a screenshot would be "screenshot of the gameplay".
The alt-text feature is intended for on-page images that are used to convey meaning. Screenshots on the other hand, as handled on Itch, are a separate area that have an advertisement function, but they do not change the meaning of the description, if they are exchanged with newer screenshots or different screenshots. So describing them, to describe the game is kinda moot, since that is the purpose of the description.
You do not have on-page images on your page. You do have one on your devlog though. Could you not use the alt-text feature of html with the edit function of Itch, or was it deemed unhelpful?
As I have pointed out, no one hinders you to design a regular html page, complete with regular alt-text for your embedded on-page images. There just is no alt-text feature for the designated screenshots.
Or is the alt-text really disabled in the description? I always thought except for css and js, it would have regular html capabilities.
