Sure, here's an example of a simple merge game implemented in a single HTML file:
This is a basic framework for a merge game where you can move tiles in four directions (up, down, left, right) to merge them and increase your score. However, the actual implementation of the game logic (moving tiles and merging) is left as a placeholder in this example. Feel free to complete the `moveUp()`, `moveDown()`, `moveLeft()`, `moveRight()`, and `checkGameOver()` functions according to your desired game rules and mechanics.
