Very cool — I love it:
Inspired by Dutch artist M.C. Escher, Devil’s Tuning Fork (DTF) challenges players to rescue children whose spirits are trapped in a lightless – and sightless – 3D world. Created by a 15-student development team in DePaul University’s Game Dev program, the free PC game was developed in less than five months, with students working nights and weekends in the University’s development and animation labs.
In DTF, creative graphics and immersive sound design turn the typical first-person shooter upside down. Instead of shooting their way though the map, players must navigate a dream-like maze guided only by the sound waves emitted by the Devil’s Tuning Fork. The game has players “see” through a simulation of the echolocation perception used by dolphins and bats, a mind-bending twist on the FPS genre.
