Best interactive book Ive ever caused fractures in the spacetime continuum with.

Its easy to understand - well, about as easy as understanding the fourth dimension gets - and the interactive parts are wonderful. The writing is especially good! I was actually laughing out loud at most of the comments; it feels almost like Douglas Adams or the Welcome to Night Vale writers had a hand in this.

Overall, absolutely lovely app. Now if youll excuse me, I have some tesseracts to operate.
