Hi there folks,
I'm happy to have been able to help and hopefully this will enable more folks to play your Games since here on itch.io, there are no such restrictions in place so far and therefore it is my main source for buying and playing adult games.
Another option I have found from some creators, who are not present (yet?) here on itch.io, also use Patreon for distributing their Adult Games there ("Bonfire", "Lust for Adventure" for example).
Therefore, it seems that merely Steam is limiting its (International) Audience (in some places) so restrictively - whether itch.io or Patreon have different legal relations, haven't been obliged by such strict requirements yet or whatever reasons are and may be involved there, I have really no clue (yet - even though I'd be curious to find out, if there have been journalists trying to investigate that already, for example).
But I'm glad you could appreciate my feedback since I would truly like adult games - like yours - to be more easily available legally and with financial appreciation for all the work you've been doing.
There are download portals where maybe older versions of some Games are available, too, but they naturally lack the possibility to reward the artists/creators for their work and only serve to spread the word about the existence of Games (why I'm glad many creators here offer public versions (usually with older and outdated or at least limited content - serving as "Demo-Versions") as well as paid "full" versions of their Games.
The only thing I am not certain about is, whether or not the other countries with similarly strict restrictions (maybe [South-]Korea, too and Japan?). It would be quite interesting to know from residents from other such countries if they can access the adult games sold or offered for free here on itch.io and Patreon for that matter.
Cheers and hope it helps you in making your Game(s) more available to a larger audience (which is always good for you, too, of course ^_^ )
