Sure! Here's an example of a simple 8-bit platformer game implemented in a single HTML file using JavaScript:

This HTML file sets up a canvas element for rendering the game graphics. It implements a basic game loop that updates and renders the game state. The player can move left and right, jump on platforms, and falls down due to gravity. The game features simple 8-bit graphics using colored rectangles. To play the game, you can open this HTML file in a web browser, providing a suitable environment for running the JavaScript code. On a smartphone, you can open it in any suitable browser app. Please note that this is a simplified example and can be further expanded and enhanced depending on your requirements.
