Alt-G is a lateral thinking puzzle game built entirely around the hardware features of a mobile phone. Levels use smile detection, voice recognition, handwriting recognition, motion sensors, multi-touch, the microphone, and the camera to create puzzles that have no equivalent on any other platform. Each level is a standalone original mini-game, with new ones added over time. Completing all of them earns a Creative IQ certificate. Developed by a solo indie developer, with all levels available without payment.
