Build a Web Game: Alien Invaders Game

The author built a web-based game called "Alien Invaders" for the Web Game Challenge, Build a Game: Alien Edition. The game involves controlling a spaceship to shoot down incoming alien enemies using arrow keys, mouse, spacebar, or mouse click. The game features multiple levels, power-ups, and a boss enemy to enhance gameplay. The author started by setting up the basic HTML structure and styling using CSS, then used JavaScript to create the game logic. The game logic includes player movement, shooting mechanics, enemy spawning, collision detection, and scoring. The author also added a pause/play functionality and power-ups to the game. The game loop is managed using requestAnimationFrame for smooth animations. The game is available to play online, and the source code is available on GitHub under an MIT license. Building the game was a fun and educational experience, teaching the author about HTML5 canvas, JavaScript game development, and handling user input. The author plans to add more enemy types, improve graphics, and implement a high score system in future updates.
