Sure! Here's a simple implementation of Pac-Man with a spike ball obstacle. Please note that this code snippet is just a basic example and may require further improvements and enhancements to be a complete, fully-functional game.
In this implementation, you can control Pac-Man using arrow keys on your smartphone screen. The objective is to navigate Pac-Man through the maze without colliding with the spike ball or ghosts. If Pac-Man collides with either the spike ball or any of the ghosts, the game resets, and a "Game Over!" alert is shown.
Please note that this implementation doesn't include advanced features like scoring, additional levels, or complex ghost behavior. It's a simplified version to demonstrate the basic mechanics of the game.
