SARKWO comes from Kishor Berde. The object is to slide the colored tiles to get to their targets.
It reminded me at first of an old java game that was a multi-ball maze.  This game goes pretty fast.  And then things get more interesting with wormholes.

The very last level took me a long time. I kept finding my pieces in the same unsolvable situation.  
My only regret is that I played this game on my tiny phone.  I would like to see some more levels similar to that last one!

(Hey!  You've probably noticed that I've slowed down my review of puzzle apps these past 2 months.  All is good. I'll try to post more frequently.)
