The raven waiting outside is a good one, thank you. Yes, as you can imagine, the game is not well optimized, but there are many things I can do that don't take too much time to implement and could improve performance, like the maximum spawning number, which I will include in the next release. Initially, I intentionally made the raven go through some walls just to discourage people from staying inside the building for too long, but as you said, there are many other ways to make them go outside. Thank you for the feedback; it's always appreciated
