Sure! Here's an example of a platform game where a dad collects milk and avoids monkeys:
To play the game, you can copy the above code into a new HTML file (e.g., `platform_game.html`) and open it in a web browser or on a smartphone. The game canvas will appear, and you can control the dad character using the arrow keys (Right and Left). The objective is to collect the milk while avoiding the monkey. If you collide with the milk, you win and get a congratulatory message. If you collide with the monkey, you lose and receive a game over message.
