+**Turtle Crossing Game**  
+
+**GOAL**  
+The Goal of this game is to create a Turtle Crossing Game. 
+
+**DESCRIPTION**  
+In this game, turtle has to cross the road, with running cars safely. If road crossed safely, turtle moves to next level, with even faster cars.
+
+### LIBRARIES NEEDED
+
+1. Turtle: provides a powerful graphic tool.
+
+**WHAT I HAD DONE**  
+1) Create a turtle player that starts at the bottom of the screen and listen for the "Up" keypress to move the turtle north.
+2) Create cars that are 20px high by 40px wide that are randomly generated along the y-axis and move to the left edge of the screen. 
+3) Detect when the turtle player collides with a car and stop the game if this happens.
+4) Detect when the turtle player has reached the top edge of the screen (i.e., reached the FINISH_LINE_Y). When this happens, return the turtle to the starting position and increase the speed of the cars.
+5) Create a scoreboard that keeps track of which level the user is on. Every time the turtle player does a successful crossing, the level should increase. When the turtle hits a car, GAME OVER should be displayed in the centre.
