Number None. (2008). Braid [Video game]. Number None.

Braid is an indie puzzle-platformer video game developed by Jonathan Blow and released in 2008. It is notable for its innovative gameplay mechanics and philosophical narrative. Players control Tim, a protagonist searching for a princess, navigating six distinct worlds, each introducing unique time-manipulation mechanics. The player can rewind time indefinitely, which becomes central to solving puzzles and overcoming platforming challenges. Each world features different time-based mechanics, such as objects immune to time manipulation, a shadow that replicates prior actions, and time linked to Tim's position. The ultimate goal is to collect puzzle pieces scattered throughout the levels to complete jigsaw puzzles that reveal aspects of the storyline.

The game's narrative is intentionally ambiguous, exploring themes like forgiveness, desire, and regret. The final level introduces a twist, showing Tim as a potential antagonist in the story. This has led to various interpretations of the plot, including one associating it with the development of the atomic bomb.

Developed over three years with a budget of $200,000, Braid features hand-painted visuals by artist David Hellman and a soundtrack of licensed classical-style music. The game's art and music contribute significantly to its tone, immersing players in its reflective and intricate world.

Upon release, Braid received critical acclaim for its innovative mechanics, challenging puzzles, and artistic design. However, it faced criticism for its short length and high price. It is considered a landmark in indie game development, influencing the industry and subsequent indie titles. A remastered Anniversary Edition was released in 2024, featuring updated visuals, additional levels, and developer commentary.
