After 4 years, I finally did the Snake game. Since I started programming (almost 4 years ago), I dreamed of doing this game, but I never did it.
Now the game has 2 versions: Procedural programming version, and Object Oriented Programming version.

Code:

• Generic programming version
• Object Oriented Programming version
• Add a settings.json to edit the settings of the game
• Comment the code

Game stuff:

• Collision with the borders of the window
• Scores
• Change the font

In the folder, there is a file called settings.json. Inside of this file, there are settings that can be changed.

• "scale" : 10 - This changes the scale of the whole game (the size of the grids).
• "initial_snake_size" : 5 - This changes the initial snake size. How many squares you want the snake to begin with
• "fruit_color" : [0, 255, 255] - Set the color of the fruit. By default it is cyan, but you can change to any color in RGB
• "snake_color" : [255, 255, 255] - Changes the snake color
• "frame_rate" : 15 - This changes the framerate of the game. the higher, the faster.
• "song_path" : "./song2.wav" - This is the place where you can change the song that is played. There is 2 songs in the main directory: song.ogg and song2.wav. song.ogg is a song from Super Mario Land and song2.wav is just a song that I found on the https://modarchive.org/ called "android - city of the night".
• "screen_size" : 300 - This setting changes the width of the screen. Don't worry about the height because the game has an aspect ratio.
• "collide_on_walls" : false" - Change if the player will lose if it collides with the walls or not (this option is only available for the object oriented version yet)
