In this game we used a genre similar to "Doodle Jump" to teach numbers to children aged 3 to 8. We used a method that lets children learn how numbers are written, how they are pronounced, and how to count correctly up to 100. The game's story goes like this: our main character wants to reach the sun, and there is only one way to do it! He must jump across clouds with numbers in ascending order! If he jumps on the wrong cloud (wrong number), he will fall — but he won't lose a life. He can jump across the clouds again, and he wins when he reaches the sun!
