Experiment - Explore Sanity Island's 9-Step Journey
Explore the island to find steps 1 through 9. Right click the number ('9' as seen in the image below) to receive a notecard about the corresponding step in the 9-Step Journey.
Hint: click the 'Keep' button and the notecard should automatically open. If it does not, you can find it in your Inventory - click the 'Me' tab in the upper left, then 'Inventory' and then open the 'Notecards' folder under 'My Inventory'.
