The Spidewick Chronicles: The Siege On Spiderwick Mansion.

You control a character, likely Jared Grace, from a fixed position inside the mansion. Your view is through a window, and you use the mouse to aim and click to fire projectiles at the goblins and other monsters climbing the walls outside. The main objective is simple: survive each wave and prevent them from breaching the house. Between attacks, you might manage a limited supply of ammunition or activate occasional power-ups. The pacing is relentless, with little downtime as more enemies appear, and the difficulty builds steadily. It feels like a tense, repetitive task of precise clicking and target prioritization to keep the horde at bay.
