[Update] Abstract rhythm platformer 140 coming to Playstation Vita and 3DS courtesy of Double Fine
Abstract game by Abstraction Games
Double Fine is publishing a new rhythm platformer for Playstation Vita that looks minimalist in the nicest way possible.
Developed by Abstraction Games, 140's simple art style means that you're just focusing on the music and its integration with the platforming aspect of the game.

Indeed, the game's music and rhythm changes what moves and what disappears so you'll have to study every pattern of the beat to understand how to proceed onwards.
140 is actually a winner of the IGF and came out on PC in 2013.
Its out this summer on Playstation Vita.
