It's amazingly nerve-wracking and I love it. The dying process feels less mechanistic and far scarier, leads to players respecting the threat it poses.

Mothership does something similar, when someone goes down you roll in the dice in a cup and turn it over so no one knows the result unless they spend a turn doing triage. The drama is so intense since the situations are usually really frantic.

Oh, that’s fucking evil. (Lawful evil, to be sure, but still evil)
