Numbered balls are falling and coming. Catch or avoid, and you just gotta make 20. (For example 3+3+14, 6+7+7 ,and more combination of numbers which makes 20 as total) Don't get more than 20! Left and Right arrow keys to move Up arrow key to jump Catch a ball - 1 Make 20 - 20 (There's no 1's or 2's anymore)
