Cookie Clicker was initially made for laughs, the whole gameplay loop mostly expanding on the lollipop farm feature in Candy Box:

(as a sidenote, the reason i’ve promised a dungeons minigame for about 10 years now is entirely because Candy Box had them)

the game’s current presentation and design logic stem from the years i spent as a kid playing old macintosh shareware as well as my interest in skeuomorphic UI. if you browse through Macintosh Garden long enough you’re bound to find some of the stuff i obsessed over between 7 and 17 and i’m sure a lot of it has subconsciously found its way into the way i make my games.

some of Cookie Clicker’s major features originate from early player suggestions and from reading discussions about the budding idle game genre, ie. the prestige/ascend system was added after i read people discussing a flash game named Kaguya Table (which involves a feature called “mastery”):

the ascend screen itself takes after Path of Exile’s passive skill tree:

i’ve been asked before where the creepy grandmapocalypse body horror idea comes from and for the most part the answer is i’m just kind of a little freak like that. Cookie Clicker’s initial “made-in-4-hours” version ended with the grandma building going bonkers and replacing the whole background. i’d been into Junji Ito and similar things for some time at that point so turning it into a whole thing for the “i’m making this game seriously actually” version felt like a logical step. pretend the Junji Ito image i’m including is from his gorier stuff

finally, the kitten upgrades and possibly the whole “achievements grant milk” thing were added at the insistent request of a tumblr user who really really wanted me to add cats to the game somehow.

if you were specifically curious about the news ticker at the top of the game, i more or less directly lifted that from the one in SimCity!
