Sure, here's a simple game implementation that meets your requirements:
🔴
❣
To play the game, simply copy and paste the above code into a new HTML file and open it in a web browser. The game will start immediately, and you can tap the red stickman ("🔴") to move it around. The game gets harder as the stickman grows bigger every 10 rounds. If the stickman collides with the red lasers ("❣"), the game is over.
