Xun started vaping last year, she said, as a way to begin the process of quitting cigarettes. She also has a “bunch of friends who vape,” many of whom “are very attached to their vapes.” But she’s not naive about vaping’s well-documented risks, and began to wonder if “gamifying” her nicotine use might help her disincentivize it. In the first iteration of the project, hitting the vape would actually murder the digital pet, and thus would ideally work to guilt-trip the user into not inhaling.

“There’s a big trend of parental locking yourself,” Camacho added. “I’m locked out of certain apps behind a password that Rebecca knows, so I don’t scroll Instagram too much. It would be cool if you could have that for nicotine.”

But then, explained Xun, Camacho “found this Stupid Hackathon. And we were like, it’d be kind of funnier to be evil.”
