A story about a math teacher named Branny who lives in a schoolhouse. She has a granny-like appearance and is known for her scary stories and the puzzles she gives to the students.

Branny is a very frightening character, and she has a very interesting story to tell. She is not your typical teacher, and you will have to go through the story to find out what she is really like.

The owner of the schoolhouse is Branny Granny, who must keep the building safe because she lives by herself. You must locate several keys in order to leave her house through the branny granny exit. You need to get out of the branny-grandma mansion, and to do that, you’ll need to use all the keys you have to finish the objectives and open doors.
