That's a lot of words! it seems like this is coming along nicely. I don't know where you do your typing (if it's in the browser or a word processor), but I have my docs saved into a dropbox so everytime I save the file it autosyncs to the dropbox cloud. it doesn't have to be dropbox but some sort of cloud saving might be useful for you if the computer crashes a lot. this is assuming you have an internet connection & a computer that can handle syncing all the time (the syncing part does tend to slow down my old laptop unfortunately :( but for a simple word doc it shouldn't be too bad)

I've tried writing in Notepad++, but now I work in the program itself; this game has minimal coding but I still manage to botch it sometimes, and the colors it automatically turns the code help me know when I've wanged it up. And I have the file backed up to my dropbox, but OG Twine doesn't autosave the way Twine 2 does, and I foolishly didn't save even once as I was working last night ╮(´Д` ╮)
