Minor gameplay tip (very small spoiler)

For people who are struggling with getting enough memories to level their skills: there's a handful of memories you can get *very* quickly: Memory of salt (moon, knock, and winter) can be gotten by throwing anything into the sea (including a glass of water, which you can get trivially once you unlock the well), Memory of sound (heart) can be gotten by throwing things into the well, and Memory of sight can be gotten by burning things in any fireplace. A slightly less advisable one is releasing animals along the coast for a Memory of hindsight (scale and winter). All of these take a mere 10 seconds and do not require any soul card, so they're great for when you're approaching midnight and just need one or two more memories.
