It is a fun puzzle game that involves liquid physics.
Each chapter portrays different scenarios with different liquids and each one makes an interconnection to the other in somehow. This makes an interesting story to follow.
The game has several kind of liquids, each one with different characteristics like viscosity and velocity over different surfaces.
A negative point is the lack of controllability. You can only tilt your screen to the left or right and this give you low control of the fluids.
Some levels can be very frustrating because you have to memorize the entire level in order to complete it. But that's not so difficult to do it.
There are very interesting achievements to unlock. The most difficult one is to earn all 48 gold medals. This requires you to finish all levels carrying as much fluid as you can on the lowest possible time.
