#Create an etch a sketch turtle game

#The turtle should move with the arrow keys (up, down, left and right), and draw

#Space should clear the screen

#o and p should make the pen size bigger and smaller

#u should pick the pen up or put the pen down

#All code must be commented

#BONUS

#Add a feature to change colors
