Sure! Here's an example of a simple survival game implemented as a single HTML file using JavaScript, enclosed in script tags. Please note that this is just a basic demonstration and not a full-fledged game.
This code sets up a basic survival game where you control a player represented as a blue rectangle. The player can move using the arrow keys. There are two resources to gather (wood and stone), and by reaching the top-right corner of the canvas, you can gather wood. The game includes a basic UI to display resource amounts.
Please keep in mind that this is only a starting point, and you can further expand and customize the game according to your requirements.
