Hey, I downloaded the game to test it out. All NPCs are hostile. Fighting seems to work. However, as soon as I try to flirt, IDLE appears in the top left corner and I can't do anything else. All buttons are disabled and you have to restart the game. But it's always the same result. It doesn't work. Or maybe I just don't understand how it's supposed to work.

same here

Same issue here.  NPC's all automatically hostile.   Beating an NPC and attempting to talk to them will break the game.  Please update and fix since I'd rather help support you.
