Rainbow Castle

Rainbow Castle was one of those simple, colorful games you'd find during the Flash era. It appeared online around the mid-2000s, a time when many small, browser-based games were created by individual developers. The game had a straightforward premise that felt typical for the platform.

You control an angel named Shena, moving her left and right with the A and D keys while jumping with W. Your main goal is to defend Rainbow City by fighting off incoming enemies. You attack by pressing the spacebar to fire rainbow-colored projectiles, and you can use the enter key to clear the screen of certain obstacles or effects. The pacing is steady, with enemies approaching in waves that gradually increase the challenge. It feels like a light, reactive arcade game where your focus shifts between positioning, timing your jumps, and managing your shots. The experience is defined by its basic controls and a direct, uncomplicated loop of action.
