I was looking to speedrun stimulation clicker but realized that there wasn't a category for it, chances are that the only neal.fun game on here is the password game, this is a petition for more neal.fun games to be added to speedrun.com

You can request the game yourself. Submit a support ticket (Help > New ticket) under "Add a new game to Speedrun".

Also read the game request rules https://www.speedrun.com/support/learn/requesting-a-game and there are a few more rules on the ticket request page.
