TouchTone is a 2015 puzzle video game developed and published by Mikengreg, a two-person indie game development team made up of Mike Boxleiter and Greg Wohlwend. The player monitors phone calls as part of a government surveillance program to find public threats. They unlock chains of emails by completing a series of puzzles in which a beam is reflected around a room to a set destination. TouchTone's core concept grew from a two-day game jam immediately following their 2012 release of Gasketball but only found its hacker theme following the mid-2013 global surveillance disclosures of Edward Snowden. The tone of TouchTone's story grew from satirical to serious over the course of the game's development.
The game was released on March 19, 2015, for iOS devices. The review aggregator website Metacritic characterized TouchTone's reviews as generally favorable. Critics praised the game's visual style and story but criticized the way the game did not allow players to skip puzzles. Reviewers found the light-bending puzzle premise unoriginal but appreciated its thematic connection.
