Thanks for your reply, is there a way to remove the NSWF? As the game is a demo and has no NSFW content, I've updated the description.
Remove all adult content tags and descriptions, and then, in the metadata section of the dashboard, uncheck the option that says "Has sensitive content."
After that, you'll have to wait for the staff to review it. If they don't, contact them again and clarify that the content is just a demo without NSFW content.
