Well, you could ask the creator of the game.

Thats the type of comment you would place on the game creators profile. But even then, they dont have to make another if they dont want to, so...

Generally, if you want something, you have to go pay for it. Find the developer's site, figure out if they have an email address or a way to donate, use either to point out the need for a new game and mention the money you will pay for them to do that.
If you are not willing the donate, you just have to wait for it like the rest of the internet.
