Loved the game, I got to (rot13) avargl-frira files and I found it (as others put it) challenging while not frustrating to work out, which is the best place to be; sad that my impatience rushed me to the comments before I could reflect on the mechanics of the curse and the dynamics of the ending.

Re: the (rot13) qernz file, I think I should go back and understand how to get there without help.
Thanks so much, dear author and fellow players!
