I've been too distracted by other things (especially getting more regular Baldur's Gate 3 and Civilisation 7 sessions going with friends) to properly lock in and learn Sekiro. I did recently pick up Death's Door, though, so that might make for an easier-going one for now - plus, of course, some fabulous Seamless Co-opping on Elden Ring
I'm personally a fan of reducing runbacks for the most part. I get the idea of the challenge, but in most cases you can optimise a long runback far faster than you can optimise the bossfight behind it, and after that it just becomes a chore. I think it leads to un-needed and un-fun frustration with difficult boss fights if you find yourself dying in the bossfight in less time than it takes you to actually return to the boss fight
