I went through and also added all the descriptions for the new rooms. This was a fairly simple task because it's something I've already done many times. It was really just time consuming because there are so many areas the player could click on.
The biggest thing I did this week was messing with the book shelf. From the beginning of this project I wanted that bookshelf to display a menu of options for the player to click. I wanted them to be able to select the book they wanted to know more about. This was incredibly difficult because most tutorials are set up for actual conversations with other characters. Mine was basically a conversation with a book shelf. I read a few tutorials and forums and also watch a tutorial on dialog to figure it out. I never found anything about objects rather than characters, so I just kind of messed around with it until it worked and eventually that worked!
So now the game is able to be played completely through, with the new downstairs areas. I need to add some sound to the downstairs room and even a reaction for the first time you enter them, but that will be another time. It's 2 in the morning and I have worked on this all day!
I also created another video that shows the progression of the game from the early weeks of development until now!
