Since it wasn't clear, I tried it again. I think it happened right when the message was about to appear. Last time, the message wasn't displayed on the screen, but this time it froze after the message appeared and closed.
Yes, that's right. I've just checked and figured out what you're talking about. After the player starts playing as a villager, the timer starts counting down at 3 minutes. When the time runs out, a game end notification message should appear, but it does not appear in the current version.
