Persistent Levels in SMBX2?

[EclipseMain]

Is there a way to make changes in a level remain after you leave the level and enter it again?

Like for example, if you hit a block and it has an event where it hides a layer, if you exit the level and enter it again the layer will remain hidden. Can you do this in SMBX2?

You can use SaveData variables to store some kinda information about persistent going-ons, and then in onStart of the level check the status of your variables and manipulate in-level things accordingly (like hiding a layer or something).
