Agh! Zombies

You control a lone survivor in a small, top-down arena. You move with the arrow keys, shooting zombies with one button and using a melee attack with another. The goal is simple: survive each wave. The zombies shamble toward you from all sides, and you have to keep moving, weaving through gaps while picking them off. The pacing is constant, and it gets difficult quickly as the horde thickens. It feels frantic and direct, a pure test of your ability to maneuver under pressure.
