Please note that the above code assumes you have an image file named "emozi_himawari.png" in the same directory as the HTML file. Make sure to update the image source `sprucePlanksImg.src` with the correct path to your image file.
This code sets up a simple game where you control a spruce plank using arrow keys on a smartphone. The game canvas is a 400x400 pixel area, and the spruce plank is represented by an image. The `moveSprucePlanks` function is responsible for updating the plank's position based on the arrow key pressed. The `updateCanvas` function is used to clear the canvas and redraw the plank at its new position. Finally, the game starts by calling the `startGame` function which sets up event listeners for key presses and calls `updateCanvas` at regular intervals to create animation.
