Unfortunately, I do not have Twitter. I do have a mastodon that I don't use all that much @filiaa@gamedevalliance.fr, if that can be of use.
Otherwise, I guess one of us can create a draft on itch.io and add the other as admin, and then we can destroy the project once it has passed its usefulness.
And of course, you can send it to someone for proofreading/a trusted opinion.
