Honestly, aside from Visual Novels pretty much ALL IF's on here are either dead or on year long breaks. Off the top of my head I can think of maybe four that are actively being worked on,
It's annoying that outside of Choice of Game's there's so few completed text-based IF's :(
I follow a few on Patreon that are very active: A Tale of Crowns, Crown of Exile, The Bastard of Camelot, When Twilight Strikes, Crown of Ashes and Flames, and The Abyssal Song.
After The End, Within Your Eyes, and The Kings Hound are a bit slower, but they are still active as well.
Crown of Exile is complete, but you have to download it from an App Store, I believe.
