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.)
