Welcome Kynes, been following your work for a while now so it’s quite the pleasant surprise to find you here on this forum! As for publishing advice, I would say that you could create a post about it here on the forums under “projects”. A good format would be to add an image of the game, a description of what the game is about, a list of fetishes/elements, and then of course a download link. You could create an Itch.io page for the game and link to that, or just upload the game to MEGA and post a download link on the forum post.
Nice nice! The plan is to upload it to Itch.io. but I’m not super familiar with them either! I’m going to make an effort to get to know know both Itch and Weight Gaming a bit better.
