The problem the manga had was how bad the reception was in itself. At first, we see Mado wandering around her dreams, and besides a few things, nothing is explained. Then, people get mad that Mado talks, that nothing happens, and other stupid shit. We have a hiatus, and suddenly, everything has a much faster pace, shit happens, and it ends in a completely convoluted mess of chaos and unexplained things. Of course, people still complain about it, not realizing that the manga was probably intended to be much longer, have Mado become more introspective with time, and show us the big world of her dreams (think about what chapter 4 was), and that it was them who forced the writer to cut it short, leaving no place for development and explanations.
