Already had this.

Optional (cat) challenge quest for people who have played a lot of games broadly like this - perhaps, like me, starting from NES Legend of Zelda -
do not die even once during the game.

Perfectly doable, not a "souls veteran" challenge.
I recall when I played this years ago I died 2 times, one was total stupidity.
Can you do better?
