140 is a unique platformer developed by Jeppe Carlsen and published by Double Fine Productions. It is available on PlayStation 4 and other platforms. The game's music synchronization is an integral part of the gameplay, and the player controls a geometric shape that moves, jumps, and dodges obstacles in time with the beat. The game's synesthesia effect is a cognitive phenomenon that allows players to experience music, color, and number-related experiences simultaneously.

The game features four levels, each with its own soundtrack. As the game progresses, the music becomes more intense, making it increasingly difficult to avoid enemies and static noise platforms. The game's design is minimalistic, with simple mechanics that make it easy to learn but challenging to master.

Developed independently, 140 is a product of Carlsen's previous works and features similar traits such as its minimalistic design. It was released on several platforms, including Microsoft, PlayStation, and Linux.

140 has been widely praised for its design and audio background. Critics and journalists have tested the game and found it to be a unique and enjoyable experience that challenges players while engaging their senses.
