Rainbow

There is a 15 by 15 field and a rainbow snake that moves in this field without stopping. You can set its direction of movement: up, down, left, right. Colored balls appear on the field, if the snake eats them, then its length increases by 1 and a new ball appears. Your goal is to eat the balls until the snake fills the entire field completely.

Eat the balls until the snake fills the entire screen.
