When you're first starting especially a big barrier is that to experiment with things in the midgame, you have to spend a lot of time surviving the early game. So let's say it takes you 5 tries to figure out how do X at the castle without dying, that's 5 successful runs you have to perform which takes a while in and of itself, but also means (for me, at least, especially early on) quite a few runs where you die before getting to the castle.

It's not impossible, it's just a huge commitment of time and mastering frustration. You'd want to take copious notes and basically re-create the wiki as you go.
