God of war 2018

Oops, so I wanted to know your opinion about a situation that is happening to me, I downloaded gow 2018 again after a little over 1 year and I managed to recover my save but I don't remember how I got there, I don't remember the controls, I don't remember anything basically and I wanted to know if I watch some videos/lives to remember everything up until that moment or if I should start a new save from 0, thanks in advance
