Some thoughts...
The critical injury table on p. 19, the "Focused" result seems a little strange thematically. It's a mixed blessing mechanically, which is fine, but doesn't feel quite right - maybe it should auto-rally?
Does the Wounded result "stack" with the Broken effect? I.e., if you're Broken and Wounded, are you unable to use a Move action at all?
Regarding critical injuries, it looks like the "negative health=instant death" rule has been removed. I think that can probably come back? It helps cover edge cases of overwhelming source of death where a critical injury table roll would be redundant or silly.
Regarding the "Mess Up" result in stress response on p. 6, I think it should be reverted to having (by default) a harsher setback than just a failure/+1 stress. It feels more thematic that once you're really stressed you start making serious mistakes; friendly fire, cause yourself an injury, etc. I quite liked that in The Walking Dead.
Other than that, eager to see the new core rulebook and expanded critical injuries, but I am liking the changes and responsiveness! Great work! Love this game.
