Quell is an app for iPad and iPhone that is "a charming zen puzzler that is sure to test your brain and capture your heart!" The objective is simple: slide a droplet around a layout of obstacles, traps and pathways, until tu have collected all the pearls. Underneath this simple gameplay lies a world of intricacy!

And I do believe the level is called 'The Arbiter"
