There are 15 levels! Level 1-5 - Pretty easy, take 5 photos and you should be good! Level 6-11 - Medium, Pokemon may attack and you will lose 1 life! Take 5-20 photos! (Random 5-20, take 20 just in case) Level 12-14 - Hard, Pokemon WILL attack and you will need to hold down the spots to stop the attack or you will lose 1+ lives! Level 15 - Mewtwo Fight! IT WILL ATTACK and you have to do the same as level 12-14 but if you fail you will die!
