No, this matches with what I’ve seen and what has been reported over on the Itch discord. I’m actually not in as bad a shape as you, I’ve come down about 50%. Something is definitely going on here. And there were major, massive shakeups in the popular rankings all across the site. While movement is constant in those rankings obviously, in three years on this platform, I’ve never seen games jump dozens of slots in one direction or the other in a single night. Either this was a massive algorithm change or it’s some sort of bug. Maybe both.
That's interesting, I have used itch as a player for a long time and never really paid attention to how the ranking worked. It just seems extreme for our game to go from the top of the popular page for multiple days (while downloads are trending up each day) and then suddenly be hundreds of rows down at the very bottom over night. Hopefully someone will chime in with an official answer soon.
