Wondering how is this game?

This video below is inspired by Phineas and Ferb , where our favorite heroes get into a parallel dimension , where things are much different , and the world is run by Dr. Doofenshmirtz . The picture captures the moment when the characters as we know them (ie Phineas , Ferb , Perry , Candace and their friends ) meet with those parallel dimension . Your mission is to search for the numbers from 1 to 24 that were hidden in the picture , but WARNING ! It's not so easy as it seems . Color numbers is very little changed versus the image colors and can be very difficult to spot . The game tests your patience and sense of observation and will be provided with a magnifying glass to enlarge and see the numbers easily . Every time you find one number you will get 100 points , and if you find more after another you will get bonus points. However, if you click wrong and where there is no number , you will not receive these bonus points , but you will return to the 100 . Success !
