To me, from the start, reading everything, trying to change some the answers to see if change something, took me 4-6 hours, i don't know if there will be many "paths" what i can say is that different answers change some things, these thing, but i believe that will have some different "kinks" for some of your choices, for example you probably can in the future change the sexuality of jane, have a relationship with some of the girls or complete avoid them, is hard to say (because i'm not the developer and i never looked at the code) but from the text and some stuff changing, look like there will some minor changes.
