Letsplaysega.com, Gamejolt.com, and Sploder.com are websites where you can play Sonic.exe. Sonic.exe was released by GameJoly user MY5TCrimson on Aug. 13, 2012. The game is based on a creepypasta story created by JC-the-Hyena.
The creepypasta story was about a teenager playing a modified PC port of Sonic the Hedgehog for Sega Genesis who then experienced a sequence of paranormal events. The game version of the story created by MY5TCrimson and a walk-through of the game made by popular YouTuber PewDiePie popularized the original creepypasta story. A sequel to the game called Sally.exe was released by MY5TCrimson on Jan. 9, 2014.
