World of Horror, also known by its Japanese title Kyōfu no Sekai (恐怖の世界), is a role-playing video game with a 1-bit pixel art style inspired by the works of H. P. Lovecraft and Junji Ito.

The player must explore various locations and fight otherworldly creatures in order to halt a looming apocalypse.

[3] World of Horror is a roguelite role-playing game, built around individual self-contained playthroughs consisting of five different "mysteries" that must be solved, each corresponding to one of five keys that are used at the end of the playthrough to enter a locked lighthouse, in order to defeat one of several possible Old Gods that is threatening the town.

[14] All of the in-game artwork was designed using MS Paint, with additional writing provided by author Cassandra Khaw.

[16] Jordan Devore of Destructoid called the game "a rare treat" and praised its modular format, as well as its "eerie chiptune soundtrack and rising tension during a long, hard-fought run," but also criticized its combat as becoming tedious over long sessions.
