Before buying the game I downloaded quite a few trials. I've had the book, which I ignored, and the vials of liquid which I ignored, and a crate containing rusty tools. Some of my villagers got sick, but they were healed.

When I bought the full version I decided to be a bit more adventurous, so I drank the liquid, and the villager got turned into a child!
I've also had a monkey mess up the table, but it was to my advantage.

My nephew has a game running of his own since yesterday, and so far he's had the book, which he read, and then wandered off and never returned, and one of his children has turned out to be a prodigy.
