Cookie Clicker has received updates almost continuously for the last decade. I don’t have the commitment to ascend but I understand there’s quite a bit of content to be unlocked there even after you’ve maxed out your first “run.”
It still peters out eventually
It seems to have been put to rest though, it used to get an update once a year or so for a while now, but as it stands the last update was in May 2023.
Cookie Clicker got me into programming back in the day! Super simple structure (back then) and fun way to experiment with coding in an interactive way with visual feedback.
