Sure! Here's an example of a simple Snake game implemented as a single HTML file using JavaScript, enclosed in script tags:
Snake Game
This game will create a game board in the HTML document where the player controls a snake using arrow keys. The objective is to eat the red food (represented as a red block) to grow the snake and score points. The game ends if the snake collides with the walls or itself. After the game ends, the player can enter their name and the top 10 high scores will be displayed in an alert message.
Please note that the high scores are stored in memory and will be reset if the page is refreshed or closed. If you want to persist the high scores even after page reloads, you'll need to implement some backend server or use browser local storage/caching mechanisms.
