Pump Up The Birds

Green birds crowd the field. Red attackers drift in erratic paths and slam into anything in range, costing lives on impact. In Pump Up The Birds, size decides which bird survives contact. A bird that grows enough can pull a hostile flyer onto your side and change its color to green. Swell it too far, though, and the next crash wipes it out. Each round ends only after the whole flock belongs to you.

How to play?

Tap your bird and pump air into it before sending it toward another flyer. Hitting a smaller enemy converts that bird into an ally, building your flock for the rest of the round. Power-ups and upgrades raise your odds during crowded clashes. Enemy waves also fling more birds into the field, which makes regular size checks necessary until the last hostile bird switches sides.
