Since you have nothing to download - there is nothing to sell - that is why it is showing free.
Once you add a package and set the operating system, then the price will show up.
In addition, while you can have pages with nothing to sell on them, they won't show up in search results until there is a downloadable package on the page.
So if you're creating a page to show other people - that's cool - you can send them a link and they can use that to look at your page.
But if you're creating a page for people here to find when they're searching for games - they're not going to find it right now.
