Simple snake game is easy to play you just need to used up key ↑ up arrow to move snake up , ↓ down arrow to move snake down , ← left arrow to move to left and → right arrow to move snake right.
13+
14+

15+
16+
- List out the libraries imported.
17+

- turtle
20+
21+
## Setup instructions
22+
23+
Download the Enhanced folder and extract the files
24+
25+
Run them by double clicking main.py.
26+
27+
## Workflow
28+
29+
- Importing the required modules
30+
- Imported snake and other object class
31+
- Create Intance of Class
32+
- move the snake and listening for event
33+
- change direction of snake on key
34+
- check weather snake eat food and extend snake
35+
- check weather snake hit wall or tail
36+
- on gameover save high_score
37+
38+
39+
## what's new in update version
40+
- Create different class for each object
41+
- seperating each class in different file
