Loopers is a Japanese science fiction visual novel developed by Key, a brand of Visual Arts. It was released on May 28, 2021 for Windows and is Key's 15th game overall. An English version was released on Steam in June 2023. It was ported to iOS and Android devices, as well as the Nintendo Switch and PlayStation 4. The story follows high school student Tyler and his friends who get caught in a time loop, continuously repeating the same day seemingly without end. Before long, they meet others caught in the same predicament who call themselves "loopers", and the two groups join forces to try to break out of the loop.
Loopers is the third of Key's "kinetic novels"—after Planetarian: The Reverie of a Little Planet (2004) and Harmonia (2016)—since its gameplay offers no choices or alternate endings. Instead, the player proceeds through the story solely by reading. The story was written by Ryukishi07 of 07th Expansion, and character design was produced by Kei Mochizuki. The game's soundtrack was composed by Shinji Orito, Sōshi Hosoi, Donmaru, Hisashi Tenkyū, Shōyu and Sumi.
