Sure, I can create a simple shooting game based on the "Five Nights at Freddy's" theme. Please find the code below:
To run this game, save the above code into an HTML file (e.g., `game.html`). You can then open the file in a web browser on your smartphone.
The game allows you to control the player character using the left and right arrow keys. Pressing the up arrow key shoots a bullet upwards. The objective is to shoot down the targets (represented by white squares) scrolling from top to bottom with the bullets.
Note: This is a basic implementation of a shooting game using JavaScript and canvas. To make it a complete game with specific rules, levels, and other features, additional coding and game design would be required.
