Uhm, I tried Nevermore a few days ago and I was really amazed. The story was confusing at first, honestly I was disturbed by Lenore's close-up there (

) but generally it was good. I think the "why Ed sounded boring" there was because he did not get good sleep. I understood that sort of remark because I myself sound bored at that kind of situation. What a concept.
I introduced this to my other friends and I replayed it for them, but there seemed to be a problem. (following is prone to deletion)
When we were at the white screen part and the findings are indicated, it suddenly said "FFI: Negative". We did not do anything actually, we just watched it (as I learned from the experience, Ren'py automatically shows the next set of texts after some time), and then we got that "FFI: Negative" ending. Then I tried to save this for future reviews, then loaded my previously-saved "FFI: Positive" ending file. When I tried loading it, however, my laptop did not respond, then a new set of three save files were shown. I tried loading these files but the laptop seemed stuck, so I tried the usual... Ctrl+Alt+Del... but without doing anything yet, the program suddenly terminated. A "traceback.txt" popped, telling that there was an "uncaught exception" in the script. It says something like, "_restart is not defined".
I really thought that this has only one ending, but it seems that I should explore more.
EDIT: (for not reading previous posts)
Oh, so there are multiple endings, but I hope you'd still read the spoiler part. Gomen.
