Crossing the Turtle : Python Turtle Project for Beginners

 

Game Rules:

1. One turtle of unique color can only move forward.
• Neither left nor right. Turtle cannot even move backward.    
2. Turtle has to save itself from the collision with cars.
3. If crosses all the cars, its level increases & along with all the car's speed!
4. Random count cars & each car of random color are coming from the left & right.
5. The scoreboard is maintained for every level.

How the game looks like?
