A Map?

I’d like to make a map, but I’m not sure how, I want it to show the current level and have the ability to be clicked for warps. This might be done in the user interface, But i’m not sure.
Anyone know?
here’s my game- https://flowlab.io/game/play/1068924

It would be best done on the UI for ease of clicking on the map and always in front and center of the screen.

But, how do I make it an expandable thing?

You can use number and size behaviors to do that. They just have to be triggered by a certain action by the player. For example, clicking on it or pressing a key.

Do you have an example?

No, sorry.
