Shoot Zombies With Guns

You control a character inside a multi-story building, using your mouse to aim and fire at zombies that appear in the windows. Your goal is to clear each floor before moving up to the next. The mechanics are basic: you click to shoot, and you need to be quick because the zombies don't stay visible for long. The pacing is fast, and the difficulty comes from their increasing numbers and the need for precise timing. It feels like a tense, reactive test of your aim and speed under pressure.
