Enjoying this so far! Just got a couple things to say:
First, I managed to softlock the game by accidentally hitting the emote button while in a dialog.
Second, I've been seeing NPCs out in the wild just break entirely and stop responding to emotes.
Third, I've had a number of NPCs either get hostile after emoting at them and in one case right after blowing me (with a "get fucked!" dialog bubble). Is... that something that can happen? Feels like a bug.
