Manifold Garden is a puzzle video game developed by American artist William Chyr.

[5] The game takes place in a "universe with a different set of physical laws" where the player can manipulate gravity, being able to "turn walls into floors".

[7] Later puzzles will involve growing trees and natural elements to bring life back to the "sterile" world.

Seeking to change his work with sculptures, and finding other mediums cost-prohibitive, he decided to move to a video game with no space limitations.

[7] Chyr observed that some have called the game taking place in non-Euclidean geometry, but he asserts Manifold Garden uses "impossible geometry" in Euclidean space, employing a method of world wrapping in three-dimensional space to make the world appear infinite.

[13] A core part of Chyr's design for the game was to leave it absent of any explicit instructions, using an initial puzzle that required the player, in order to activate a button across a chasm, to jump into the chasm and land on the other side as a result of falling through the game's repeating geometries.

[13] His team early on had discovered that playtesters would often become confused in walking around the various levels, combined with the shifting changes in gravity.

[13] He had become concerned at this time by industry fears of a possible "indiepocalpse" due to possible oversaturation of indie games and was not sure if Manifold Garden would reach completion.

Chyr was also inspired by the films Inception, Blade Runner, and 2001: A Space Odyssey, the books House of Leaves by Mark Z. Danielewski and Blame!
