Flappy UFO asks one question: how many cows can a flying saucer collect between hostile space towers before physics wins? Tap to fire the hover-jets, drift between the blinking towers, keep the plasma meter charged — and yes, the combo pickups really are floating cows. Missing one hurts your multiplier and, frankly, your conscience.
Every UFO needs a hobby. Mechanically, cows are this game's combo pickup: each one beamed up raises your score multiplier, a missed cow resets it, and in Streak mode a missed cow ends the mission outright.
The saucer wobbles and each hover pulse lifts less — you'll feel it before the meter reads empty. Plasma cells are cyan canisters with a green core; grab them on your flight line whenever one appears.
The Green Moon is deceptively soothing and the Ice Moon is the real test — pale towers on a pale sky. Use the red warning lights at the gap edges as your aim points when everything turns white.
