Hyper P.T. was made during the Merveilles HyperJam, during which dozens of small games were made using HyperCard, an old development tool for Macintosh computers that used hyperlinks (yes, those hyperlinks) to thread together elements to create games. Myst was one such game, and Hyper P.T. definitely shares some DNA with Myst in the manner in which you explore the house.
Low-fi horror games are pretty popular, with the most recent cult hit being World of Horror. Like Hyper P.T. that too was made using an unconventional tool: Microsoft Paint.P.T. has had several remakes over the years, including a full VR remake created in Unreal engine, and a demake that imagines P.T. as a PS1 game. For more on how it became such a cult hit, see our story on how P.T. redefined urban legends for the 21st century.
