Probably you have already noticed but I found out that in the save1.dat file (or any other savefile) are stored the actual read lines, and I found only two possible outcomings:
1) if you save before the end of the part with Dlanor and Gertrude (doesn't matter the line) and you load that save it always start from the begging as if you have started the chapter from the main menu;
2) if you save after the initial part with Dlanor and load it will always restart from the line: "This.... is a curious fragment".
Right now it's probably a non-issue because it is a demo and 99% of the readers are not going to save and they will just read it in one go.
By the way I really liked and I'm really looking forward to the complete release.
