Sure! Below is an example of a simple frog game implemented as a single HTML file with JavaScript:
🐸
In this game, you control a frog (represented by the
🐸 symbol) using the arrow keys on your smartphone. The frog can move up, down, left, and right within the game window. The frog's position is updated based on the arrow key pressed by the player.
Please note that this is just a simple example, and you can modify and enhance it according to your specific game requirements.
