Possible bugs:
1. If the game crashes after reaching 800 experience points due to a pop-up window, the game will crash if the player reaches 800 experience points, as the game doesn't level up above 800 experience points.
2. When knocking on a door, if the player is supposed to gain pink beads, the game will crash because the player can't find the data.
3. The door locations on many maps don't match the map markers.
4. Game data should be optimized. Chatting can cause duplicate loading, which can cause the player to exit the game.
