I assume that the score on the game layout is stored in a variable. If not, just add a variable on the game layout's event sheet and every tick set the variable to the score. You probably already have a text object on the final layer that says "Your score was ...", note that this object must be unique and not just the instance of a text object used somewhere else. Anyway, in the final layout's events, create an On start of layout, and add a (text object with score)>Set text. In here, you can just say "Sorry pilot" or something (if you have that text already with another object then you don't need that) and after that put an & to add up the strings, and just put in the name of the variable that you saved the score in. So it should be like this:
"Your score was" & TotalScore
In this case TotalScore is the variable.
