Sure! Here's a simple game implemented as a single HTML file using JavaScript, enclosed in script tags. The game is designed for smartphone operation and uses pictograms. The objective is to move the player character using W/A/S/D keys and avoid falling flowers to reach the flag pole. You can play the game by opening the HTML file in a web browser or by copying the code into an HTML file on your smartphone.
When you open this HTML file on your smartphone, you will see a blue player character at the bottom-left corner, and flowers falling down from the top of the screen. The objective is to use the "W/A/S/D" keys to move the player character and avoid collision with the falling flowers. The green flag pole is the goal, and if you reach it without colliding with any flowers, you win the game. The score is shown at the top-left corner. If you collide with a flower, the game ends and the final score is displayed in a Game Over screen.
