How I post an Item without an url?

So, I just now finish a game with the name "Ittle Dew".
An Action/RPG and humorous parody of Zelda games.

However there is a "Prototype" version of the game I want also include to the database.

The problem is I can't find a site related with this game.

How can I put this one here in Lista as an Item?

Thank you for your help.

Please don't. There is no way to link between Items so i might run into one but not the other. Maybe add a note in the description.

I always leave a small note right next to the title if the game is a prototype,remake,mod,etc of the original game.

Here are some examples of what I did:

www.listal.com/game/lamulana-pc
www.listal.com/game/lamulana-remake-pc

www.listal.com/game/alien-hominid-playstation-2
www.listal.com/game/alien-hominid-pc

You get the idea.

But as I said....I want to find a solution to this giant problem.....
How to put an item without the use of a url/link?

If there is no information on the game any where on the internet it shouldn't be added to Listal.
