Of course, there are some new bells and whistles on this version, called the Tamagotchi On. Like a color screen, for starters, along with additional activities and a mobile app to assist you in your adoption of an annoying, excessively demanding pixel beast (while also reminding you that you could play Pokemon instead). The overarching goal is to nurture your Tamagotchi until you can breed it with others like livestock, wave a hanky in farewell as it returns to its home planet, or simply watch it perish from the unchecked accumulation of feces in its filthy habitat.
The core elements of the original Tamagotchi remain unchanged, however. There are still just the three buttons, the classic egg shape, and a requirement to spend an inordinate amount of time fiddling with a sniveling, soothingly colored whatsit from birth til death. And that last part can happen within the space of only a few hours, should an owner, say, do literally anything more interesting with their time.
