I created a simple browser-based runner game using HTML, CSS, and JavaScript where players use the arrow keys to dodge obstacles, earn points, and try to beat their high score. One of the most challenging parts was handling smooth player movement, obstacle spawning, collision detection, and score tracking while keeping the gameplay enjoyable. I'm especially proud of building a complete playable game from scratch with clean controls and a black and white design that runs directly in the browser.
When trying it, you should know that timing and quick reactions are key!
