I've been playing non-stop for several hours, and I have a simple UI suggestion i'd like to pass on for consideration. (You guys should consider a board for suggestions, i'm not sure where to send this )
When a counterattack from an enemy would kill you, and you have death protection, it currently says "Barely Alive" - which is technically true. But I think it would be much nicer if it instead said "Death Protect" or something similar to indicate that you're about to burn off your death protection buff.
