TouchTone is a 2015 puzzle video game for iOS devices 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. The player unlocks chains of emails by completing a series of puzzles wherein 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 Edward Snowden global surveillance disclosures. The tone of TouchTone's story grew from satirical to serious over the course of the game's development.
