GamersGate has slashed 50% off of Broken Rules puzzle platformer And Yet It Moves, taking both the PC and Mac versions of the title down to just $5 as part of the digital distributor’s Deal of the Week promotion.

AYIM takes place in a world made of ripped paper, with the player using the ability to rotate the world along with more standard platformer actions to get through puzzling encounters. Also of note is the Ghost recording system that records your speed runs and places them as ghosts in friends games or vice versa as a way to compare routes.

The half off sale ends Sunday, May 9, a demo is available for download via Steam as well. From the description:

And Yet It Moves is a puzzle-platformer, set in a unique world, made of ripped paper. Within the paper collage, you can jump, run and last but certainly not least: rotate the world. Learn how to apply the physical consequences of rotation to master the many tricky situations you may encounter.

You can play a race against the clock on different levels, too, competing against previous clocked times. Your run will be recorded, as a »Ghost« which can be submitted, along with your time, to the global high scores online. You can download other users’ Ghosts to compete with friends and strangers around the world and see who found the fastest route.

Following the acclaim of the previously awarded prototype for And Yet It Moves, we present the full version, containing three exciting and beautiful environments and lots of new challenges.
