Sure, here's an example of a simple game where you control a ghost character trying to catch other ghosts:
This is a simple game where you control a ghost catcher character using arrow keys on a smartphone UI. Your goal is to catch the other ghost character. The game detects collisions between the two characters, and if they collide, it will display a "Game Over" message.
Note that this is a basic implementation for demonstration purposes. You can enhance the game by adding more features, levels, graphics, and sound effects as desired.
