The one thing that'll make me quit as a new player

It's not the skill tree, or the fact that most of the mechanics of the game aren't explained at all. It's gonna be one of two things:

- No death recap
- Trial bosses

Half the time I have no idea which of the visual vomit effects I died to, so I'm not sure what I'm supposed to learn from the experience. Related to this, how am I expected to learn the trial bosses if my progress is wiped completely when I make a mistake? I'm already punished for wasting my time, but the items are one-use on top of all that?

Everything in the game seems to encourage you to just range-spam everything to death asap so you don't have to actually interact with anything. Newer players like me are punished for actually trying to interact with and learn the mechanics. Make it make sense.
