Hexahedra

Here's an excerpt from Hexahedra's Steam description:

DESIGN: Build factories, ship cubes, and make machines dance to your industrial choreography.

REWIND: Refine your solution by rewinding the factory and replaying the action to spot potential improvements.

OPTIMIZE: Compete for peak efficiency with your friends and the world.

CREATE: Build and share your own puzzles with the built-in editor.

Cubes have become the galaxy’s most important commodity, being used as crates, musical instruments, octopus housing, sculptures, and more. Use your cube-designing skills to keep a struggling factory running, and eventually earn a post at the most prestigious cube fabricator, Hexahedra Inc. Dig into rumours that some cubes are being used for sinister purposes, and field an array of oddly aquatic requests received on damp paper in strange ink.
