What the Bus? is pure CYOA (about trying to catch the right bus to get to work) in that there are no puzzles to solve and no parser quirks. You just go through every potential story path until you find all the endings. When I was a child, I would use my fingers or paper clips to hold my place at different plot branches so I wouldn't have to start from the beginning. Joyce doesn't quite make things that simple, but the presence of an "Undo" button is incredibly welcome and makes this much more palatable.
Growing up and living in the suburbs, I have never been on a subway in my life, and only a few city buses. So I can only imagine the frustration that led to this story. Still, the snark is delivered well without drowning in it, so I was motivated to find every ending. And the choice to go surreal with many of the endings was also a treat. I don't think I would play this again, but I was grinning the entire time I played it.
