Maybe offworld? I would be interested in more answers to this question as well because I have lots of ideas for short narrative games. By way of research I went looking for press coverage of one of Angela He's games, You Left Me, which was on the front page here for a long time, so I thought it might have had some coverage. All I found was an article in PC Gamer, so maybe you shouldn't rule anything out. On the other hand, it seems likely to me that there are sites out there focusing on these types of games.
