This really goes for getting people to interact with anything you create. It's important to both lower the barrier to entry (in-browser version, tutorials, accessibility considerations, etc.) and to make it enticing (videos and gifs, boxart, general aesthetic). A jam will bring people to your storefront, but you still need to get them inside.
Just because you know what you made is amazing, doesn't mean anyone else does. It's something I need to work on as well.
