Hey leafo, thank you for answering, i really appreciate that!
I don't recall 100%, but i think i published the page first and added the downloadables about an hour later (ludum dare has a 1 hour submission window after the jam ends). Writing, Screenshot and style wise, the page stayed empty for another 14 hours or so, because the jam submission was in the night and i went to sleep then. What's really strange about it: the game did show up high on popular on the first day (5th October), and only dropped to bottom until the next day, if i'm not mistaken.
The ranking is adjusted now and shows up sensibly, thank you so much! The hot phase of the jam is over, but i'm just glad it got resolved :)
