Border Blast

You control a small ship or turret, positioned to defend your side of the screen. Waves of geometric enemies, often triangles or squares, drift in from the opposite border. Your job is to shoot them before they cross into your territory and cause damage. The controls are simple, likely mouse-aiming and clicking to fire. You manage a limited pool of ammunition, which adds a layer of tension, forcing you to make each shot count. The game starts calmly but the pace quickens as more enemy shapes fill the screen, testing your reflexes. It feels like a focused, almost methodical exercise in defense and precision under growing pressure.
