Game of Water and Keys is a funny and relaxing game that lets you fill up a glass with water and color it. With this, you can control the movement of the water by tilting your phone to the left or right. You can also disable the gravity effect and play with the level changing a bit (some sliding objects appear and others are hidden in some levels) and to advance to the next level you can only control the sliding keys or boxes.

You will also find a blue button with the letter G in all levels. This is used to activate or deactivate gravity.
