I'm trying to make a game and add a point system does anyone know go to do that

Do you mean with Squiffy or with Quest. I have a lot of experience doing that with Squiffy. If it is Squiffy, tell us what type of point system you are trying to create.

If you're talking about Quest, there's a built-in system for keeping a score. Here is the place to find a quick overview in the documentation:

There are other places in the tutorials and documentation that talk more about it, like this more detailed page:

Here's hoping these help!
