Earth Defender

Earth Defender was one of those straightforward games you'd find during the Flash era, a time when a simple concept and a few minutes to spare were all you needed. It didn't try to be more than it was, and that was part of its appeal. You loaded it up in a browser, and it just worked.

You control a curved shield, a kind of paddle, that orbits the planet. Your only tool is the mouse, which you use to rotate this barrier. Asteroids drift in from the edges of the screen, and your job is to intercept them, deflecting each one away before it can make impact. The main objective is clear: protect the Earth for as long as you can. The mechanics are minimal. You watch the trajectories, anticipate the angles, and make constant, small adjustments with your cursor. The pace starts slow but builds steadily as more rocks appear, and a single missed strike ends the game. It feels like a quiet, focused test of your attention and reflexes.
