Pixel Pigeon Protector is a city defense arcade game where players control a heroic pigeon defending urban landscapes from invading threats. Players tap to position their pigeon and automatically fire breadcrumbs at descending obstacles like cats, hawks, and garbage trucks. Special power-ups grant temporary abilities like multi-shot, speed boost, or shield protection. The game features progressively challenging levels with unique enemy patterns and behaviors. Players must strategically navigate across the cityscape, collecting seeds to upgrade their pigeon's abilities while protecting their flock from various urban hazards.
