Someone has to be the first to comment. But try the support page.
Viewing post in contact the developer
Some creators list a support e-mail. When that happens, they show up on your support page and you can contact them that way. If that's not the case, a comment is your best bet. Even if the creator doesn't see it, there are other people who play the game. Failing that, see if the creator has social media links or something. Hope this helps.
