This is a minor comment, I noticed you've capitalised the name of the top level App component file in your application, and that the other component file names (characterSelector.js, food.js, score.js, snake.js) aren't capitalised. I'd recommend sticking to one naming convention - the one that is commonly recommended for React apps is to capitalise all component names (which you've quite rightly done 👍 ) and the names of the files and folders that contain those components (Food.js, Score.js, etc.) :)
