Description

From the listing uploaded by “superpocket”.

A snake-inspired defragmentation puzzle action game! Score points by defragmenting blue blocks turning them green! Defragment 3 or more blue blocks in a row for a combo - the longer the combo, the more points! You are able to move across your own body or across the edge, but doing so will create red corrupted blocks. The hard drive will crash if you try and defragment a corrupted block! Multiplier blocks appear once you reach a certain score. Defragment it to increase your score multiplier and erase half of your body! Your special ability slows down time and allows you to fix corrupted blocks. Use it to complete some complex maneuvers or to clear out some of the red corrupted blocks! Your job is never complete! Defragmented green blocks eventually turn back to fragmented blue blocks. Do you best to get the highest score! Choose between swipe or tap controls! Complete achievements to unlock different color themes and other customizations! Can you beat the scores in the leaderboards? Achievements and leaderboard functionality requires signing into Google Game Services.
