About

Oh Flap!

Read full description

One tap. Infinite regret. Oh Flap! is the game where a tiny bird with zero survival instincts tries to navigate through pipes that have absolutely no business being there. Your job? Tap. That's it. Tap and pray. Sounds easy? Adorable. You'll hit the first pipe. 21 WORLDS THAT FIGHT BACK This isn't just a reskin situation. Every world rewrites the rules. Moonlight makes you floaty and peaceful โ€” like yoga, but with pipes. Volcano cranks gravity to "cruel" and dares you to survive. Retrowave moves so fast you'll question your life choices. Cherry blossoms drift by in Sakura while you fail gracefully. Each world has its own physics, its own vibe, and its own way of making you say "one more try." Try any world free for one game. Fall in love. Then buy it. We believe in informed heartbreak. 3 CHARACTERS, 3 MOODS Pip the bird โ€” brave, round, questionable decision-maker. Cosmo the rocket โ€” literally built for flight, still hits pipes. Hoot the owl โ€” wise enough to know better, plays anyway. DAILY CHALLENGES A new challenge drops every day. Beat it. Build your streak. Miss a day and we'll send you a notification so passive-aggressive it could be from your mother. STATS FOR THE OBSESSED Track your last 7 days of glory (or tragedy). See your average score climb. Watch your improvement trend go up โ€” or sideways, no judgment. Bar charts, play streaks, best runs, total pipes cleared. It's beautiful. Your therapist would call it "unhealthy focus." We call it dedication. GAME CENTER Leaderboards and achievements. Find out you're #47,382 globally and let that fuel your next 200 games. Unlock hidden achievements like "Belly Flop" (score zero) and "Night Owl" (playing past 11 PM, you absolute legend). iCLOUD SYNC Switch devices without losing progress. Your high score follows you everywhere, like a proud ghost. NO ADS. NO ENERGY. NO NONSENSE. No banner ads. No "watch a video to continue." No waiting 4 hours for lives to refill. You pay nothing to play. Themes and skins are cosmetic โ€” they look amazing but they won't save you from the pipes. Nothing can save you from the pipes. Oh Flap! is handcrafted with love, caffeine, and an unreasonable number of pipe-related deaths during testing. Now tap. And try not to hit the first one.
