Sure! Here's an example of a simple game where you deliver presents on Christmas using JavaScript and HTML. The game will have a time limit and a high score system. Please note that for a full-featured game with advanced functionality, you would typically separate the JavaScript code from the HTML file.
Christmas Present Delivery Game
In this game, presents are represented by div elements with a present image as the background. The player needs to click on the presents to collect them and increase their score within the given time limit. Once the time runs out, the game ends and the player's final score is displayed in an alert.
Please note that you need to provide your own present.png image file and adjust the styling based on your preferences.
