I'm on discord (I guess on "itch" there's no pm or chat-section added somehow?), while I'd just offer my collaboration for free with possibly getting nicknamed in the credits for assisting in text-translations, if that's okay? e.g. as link or info that it's about my itch-profile here, would be perfect. Because just a profile's name could be on social-media or way other platforms too, so it's easier to additionally refer to the one where players could browse if they'd be open for translating their game too.
I'd also offer translating more than just one game, and feel free to contact me in case of planning updates with additional texts that could be translated there.
