Hello, thank you for checking out our game I am happy you enjoyed it.
First of all can you tell me more about the bug exactly? since i went and played it again and it works normally.
In that part when you try to go out, the dialogue between the two plays normally then Maya moves a few steps back and Abale shows up and the game continues normally.
From what i think happened to you, you moved to the door but instead of your character facing left, you made it go down or up and the trigger of the character couldn't go back.
If you ever play it again, make sure to keep the character facing left. Since i am inexperienced with rpg maker, i am not sure to fix what to do when this happens but i will see.
