Sure! Here's a simple game where you control a character running away from obstacles. The game will be implemented as a single HTML file and will use JavaScript for the game logic.
Runaway Game
In this game, you control a player (represented by a pictogram) at the bottom of the game container, and you need to avoid colliding with the obstacles (div elements moving towards the player from the left side of the screen). To play the game on a smartphone, you can tap on the screen to make the player jump and avoid the obstacles.
Please note that you will need to have a player_icon.png file in the same directory as the HTML file to use as the player's icon. Adjust the width and height attributes of the player image tag accordingly to match the dimensions of your image.
