It definately sets a lovely scene, but I do prefer his other one:

On the game play side, cloud seems sluggish and slow by comparison... I know it was going for that, but I think there are better ways for a game to be relaxing than for it to just be... slow. It's almost forcing you to be chilled out, rather than enabling you to chill out. And by forcing you, it creates annoyance instead.

Flow, on the other hand is pretty much as fast or as slow as you like. Take your time, or hurry up, the choice is yours ohm na bee.

That's how you should do it!
