Some dialogue only appears for a fraction of a second. For instance, when the bounty hunter and "Butcher" Karoser are going from the first floor to the second, she asks him if his last name is Kuroser. He responds, but the text disappears almost instantly. 

In general the dialogue window is only 4 text characters wide, in a way that looks like a bug. 

There is also a continue dialog button, but tapping literally anywhere on the screen does the same thing.
