Sure! Here's a simple game implementation using JavaScript and HTML, where you control a character by tapping or holding down on the screen to make it jump. If the character touches a spike, the game ends.
You can save the above code as a single HTML file and open it in a web browser to play the game. When you tap or hold down on the screen, the character will jump. If the character touches a spike, the game ends, and a "Game Over" message will be displayed.
