Wondering how is this game?

Here's a game that will test your memory , you pit your ability to retain colors ! Is not, however , as hard as it looks . You will be given four images side by side , with Candace , Phineas , Ferb and Perry , each on a different background in the following order : yellow, purple, blue and pink. You have 4 different levels and each time you will remember the correct colors will fill some of the "box" level . Every time you fail, you'll have to start over . The game proceeds in the following way : we start at an easier and will become increasingly difficult . Will flash a color and it will be your turn afterwards , to give a click on the right color. If you press right , the game will continue and will become increasingly more difficult because you have to remember getting more colors . If color will flash twice , you have to press twice that color , to be fair. It is not that hard , though, because the colors are repeated constantly , just be careful !
