I downloaded on the computer mini-game "Doodle Jump". IT'S WONDERFUL GAME!!! I first saw it at my school friend. He gave me to play in this game and it interested me very-very =( . I was like a drug addict. The game is too addictive, don't play in this horror! Now i always play in the Doodle Jump on the algebra and  geometry. But it helps me to forget all my problems and does better my mood!
