Overlays cannot be customized in either 1.2.1 or 2.0 beta
however you can use the same type of system as you use for menus if you want to be able to return to gameplay from where you left off (if it’s at the end of the level just remove the scene storing)
Scene: Store Current on stack Change scene: Score page (or stats page. these will need to be scenes.)
On the Score or Stats page do most of it on the background layer then you can use actors with numbers or letter grades by them to show the score. From there you can just Change Scene to the next area OR you can use the “Restore previous from stack” to go back to gameplay.
