Jason Shiga’s Meanwhile is a choose your own adventure comic book with time travel, secret codes, mind-reading, the extinction of all life on the planet and ice cream. It is amazing. I have only played with the book a little bit but most of my attempts have ended up with everyone dead (my very first choice led to a ridiculously short story, but one in which everyone lived).
The very cool thing about it being a comic is following the line from panel to panel as it forks and crosses pages. I caught glimpses of really interesting endings, but there’s also a warning in the beginning of the book that there are endings you can only reach if you cheat. I haven’t played with it enough to really exhaust the endings, but everything I’ve done with it so far was awesome. Highly recommended.
