How can I save the score after the death of a player and restart the level with the same score after watching an ad?

Question

C++ / C#

There is a game where, at the moment of adding a button for viewing ads and getting a bun in the form of restarting the level and saving the result, the question arose of how to save the score and restart the level already with it?

PS I'm not very good at C#
