Unfortunately, I couldn’t get past the door codes. However, I later saw that you had uploaded gameplay, and even though I did the same thing as in the video, I still couldn’t move the books.
I don't know what happened. But in the build the drag and drop was not working. It is a bug in this build. I tried a lot to fix it, but I couldn't 😔😔.So I had to upload the video of the gameplay in the editor itself. If you know please do tell me how to fix it.
