Sure! Here's an example implementation of a simple 2D game called "Pirate Kings" using HTML and JavaScript. Please note that this is a basic game just to give you an idea, and it can be further enhanced and customized according to your requirements.
Pirate Kings
In this game, you control the player ship using the arrow keys (left, right, up, down) on your smartphone. The player ship is displayed in orange, and the enemy ship is displayed in dark red. The player ship is equipped with a sword, and you can rotate it by touching and dragging on the game board. Pressing the spacebar will fire a bullet towards the enemy ship. If the player ship's sword collides with the enemy ship's sword, an alert will be displayed.
Keep in mind that this is a simplified game and may not fully meet all your requirements, but it should give you a starting point for further development. Feel free to modify and enhance it as needed.
