Thought I would jump in and remind you guys that you DONT actually eat books in my game. If you tried you would either be unable to fit it in your mouth or would choke to death.
I could do something else though lol.
Perhaps add a "fiber bar" and eating books increases that.
Seems completely logical. And it would extend my hunger system to add more choices. I am totally going to add this!!!11!1111
Best idea ev-ar!
