Sure! Here's an example of a simple game that meets your requirements:
This is a basic implementation of a game called "The Haunted Underground City". It uses a canvas element to render the game objects and handles keyboard input to control the player character.
The game features a player character represented by a cat pictogram (`emozi_all/game.png`) and other game objects represented by orphan and enemy pictograms (`emozi_all/game.png` and `emozi_all/enemy.png`). The player can move the cat character using the arrow keys on their smartphone.
This is just a starting point, and you can further develop the game by adding additional features, levels, enemies, and gameplay mechanics as per your requirements.
