Sure! Here's an example of a simple Attack on Titan game implemented in a single HTML file using JavaScript. Please note that this is a basic implementation and may not provide the full gaming experience.
Please make sure to replace the `emozi_all/player.png` and `emozi_apple.png` files with your own pictograms for player and titan sprites.
This simple game allows a player (controlled using arrow keys) to move around the canvas while trying to avoid colliding with a randomly moving titan. When a collision occurs, a "Game Over" alert is displayed, and you can implement your own game over logic within the check.
Again, note that this is just a basic example and can be further enhanced and customized to provide a more engaging gaming experience.
