Pump up the birds

Pump Up the Birds establishes avian dominance through inflation mechanics. Urban territorial combat rewards size advantage—larger birds absorb smaller competitors upon contact.

Inhalation mechanics increase mass but create vulnerability window—interruption causes air loss. Strategic timing separates successful expansion from catastrophic deflation. Power-up distribution provides temporary advantage opportunities.

The competitive ecology generates persistent tension through predatory dynamics.
