Shontel The book shelves were against the wall before your change the allignment of the red books, then they "Hop" into the room . And with the sponge in this position you are perfectly trapped 😂
Those are the glitches Game Design does not think off, but they also will be amused and surprised. Depending on how many players will trap themselves like that they might have to think of a "back door" e.g. being able to change alignment of the books again and thereby reverse the move of the shelves 🙄🤔
