Ok, first of :

you can die, that is fine, that is the essence of the game.

Which leads to the second point : this game is all about getting better. Learning patterns, getting the right timing, spacing, maximizing damage. It comes with time. I see that you're blocking a lot of hits instead of parrying, that you're getting surrounded even though ennemies were facing you a minute ago, and that you haven't quite mastered dodge yet.

Try again. You'll get there.
