what is the use of spritesheet.png?

[upq]

I noticed that the graphics are drawn using code in the game, my questions are
What is the use of the spritesheet.png file?
And how may I edit the graphics in the game, change player character and ghost charecters?

Thank you so much, very clean and well done work!

You can edit charecters in file sprites.js, and use canvas draw from svg file. Insert canvas draw un function like drawPacmanSprite for main caracter.

no idea of use of spritesheet.png
