I put a few hours into this game and honestly Im not sure if I was doing something incorrectly or the game was just buggy. I back tracked a few hundred times, dunked my book things in golden water after rearranging plates, stared at a naked statue while walking backwards up the stairs, And for the life of me I cant figure out what to do.
My best guess is I was suppose to bring both books to the statue and use them there but the bridge broke and I could never get back.
So I spent the rest of the game just jumping off of railings and running around out of bounds seeing if I could sneak into a secret room. Its not a bad game but I think it could use some polish.
