[Review] Space Invaders Coded in Vanilla JavaScript (by Andrea Maille)

Space Invaders by Andrea Maille is a pure vanilla JavaScript version of the famous 2D game from 1978.

The game has the following features:

• Collision detection
• Shooting with spacebar
• Left & Right (x-axis) movement with keyboard arrows
• Peace Mode (shoot enemies with roses instead of rockets 😂)
• Timer
• Score count
• Highscore board
• Submit your score

While the game doesn’t offer much resistance in terms of the enemy A.I and lacks sound effects (which would instantly make it more addicting), it’s a great source of learning and inspiration for anyone who wants to build games with pure vanilla JavaScript.
