Sure, here's an example of a simplified game that combines elements of Call of Duty and Minecraft. This game allows players to navigate a Minecraft-like environment and shoot enemies using the controls on their smartphone.
Note that this is a very simplified game implementation for the purpose of illustration. The game has a player represented by a blue square and an enemy represented by a red square. The player can move using the arrow keys on their mobile device. If the player collides with the enemy, a "Game Over" message is displayed and the player's position is reset.
Please note that this is just a simple starting point, and you can add more features, game mechanics, and visual enhancements based on your requirements and preferences.
