Short and simple. There's no reason you shouldn't give it a play through.
The basic goal in the game is take a puddle of water from point A to point B. You do this not by controlling the puddle, but by tilting the entire level with the left and right arrow keys. It's really interesting to see how the puddle reacts as you drips through tubes and splashes against walls.
The visuals and audio are rather impressive. It's a strange blend of simplistic and stylish. It kind of reminded me of World of Goo at one moment, but unfortunately it is really short. I finished it in about half and hour.
It's not revolutionary or anything like that, but it is entertaining, especially when you see some of the levels the development team prepared. One level is in zero gravity for instance and another which was one of my favorites seemed to be inside a person's body.
Seriously, you should just try it.
