Play Bird Week (Japan) - Relaxing 8-Bit Nature Sim Online Free

Bird Week is a unique 'life simulation' game for the Famicom where players take control of a mother bird. The goal is to catch butterflies to feed your growing chicks while avoiding predators like hawks and avoiding environmental hazards. The game transitions through the seasons—Spring, Summer, and Autumn—across 999 looping levels. It's a peaceful yet challenging test of time management and reflexes, representing the early experimental era of 8-bit gaming where nature-themed sims were a rarity.
