One simple choice can change your whole journey in this wildly inventive creation from comics mastermind Jason Shiga. Make your decision and follow the path, using a system of tabs that take you forward, backward, upside down, and right side up again. Test a time machine or detonate a doomsday device. Read a mad scientist's mind or investigate the lab yourself. Every choice you make leads you down a path that could result in happiness or doom, and each read creates a new adventure!
