140 is a platform game independently developed by Jeppe Carlsen, known for his gameplay direction for Playdead's Limbo. The game is described as a "minimalistic platformer", using electronic music to create synesthesia as the player manipulates their avatar, a character that can take on several basic geometric shapes, through levels in time to the music. The gameplay has been compared to other similar games which involve music synchronization like Sound Shapes and the Bit.Trip series, though with difficult platforming elements comparable to games in the Mega Man series Source: Wikipedia, "140 (video game)", available under the CC-BY-SA License.
