Sorry for the late response myself, i've been on a trip to my grandma's house and i haven't been in touch with itch notifications, the book in the example is an image with some information and when you "Read book" it shows a text over the image, i am gladly going to help you with this problem and give you the code and i'll work on some alternative methods aswell.

You are awesome! It really means a lot to me! You see, I'm making an educational game, so books are a must by default, lol. I know some players won't be reading many pages, but I think some that will be interested in the topic will value this addition in the game. That is why I could really use your help - you are God sent. Is it ok with you if we continue this chat by emai? My mail: dejan.zivko.ffl@gmail.com
