An example of advertising I hate is the infamous "distortion bubble" of Steve Jobs, who could make you believe you he was literally creating paradise on earth.

The only thing I would add to my comment is, let people know about it where they are. I posted my project to HN because it's based on a nostalgia we all share. Find a subreddit, or a forum, or a discord/slack or something where your userbase visits regularly, and let them know.
