İmpostor Alien

A brisk arcade run for desktop, played in landscape with WASD movement. Across five episodes you guide the impostor alien past hazards while gathering diamonds, each attempt short and quick to restart. It runs in the browser with no installation, and the focus stays on clean timing rather than long-term progression.
