Hi, I am a 14 year old and i recently started learning how to use unreal engine. I was wondering how to make a game mechanic where the enemies get progressively harder and spawn more frequently the longer you survive.

Those are good references, also take a look in the Action RPG game template, it is a free asset from Epic Games (Project Template). Take a look at the file BP_GameMode. Game Mode is a blueprint where this type of combat logic is placed.
