Shapes VS. Colors

Super funny and challenging endless game.
Your reflexes should be really fast ! Focus on falling colored shapes.
Change the color of the wavy ground in time.
Make sure the color of the falling shapes are the same as the color of the wavy ground just before shapes touch it.
Otherwise shapes bounce back from the wavy ground and the game ends.
To change the color of the wavy ground : Tap one of the 4 colors. 
Good luck !
