Dog's from Space

You control a lone defender at the bottom of the screen. Your job is to shoot the waves of dogs that descend from the top. The main objective is to survive as long as possible, clearing each wave before the next one arrives. You move your character left and right, firing upward at the incoming sprites. The mechanics involve timing your shots and avoiding the dogs' return fire or their attempts to crash into you. The pacing is steady, with the difficulty gradually increasing as the patterns become more crowded. It feels like a focused, repetitive task where your attention never really wavers.
