Flappy Bird v1.5

It's been a while... SHEESH! I apologize for that. No worries though... behind the scenes, I've been hard at work!

The biggest update yet, and the final version of everything from the v1.5 betas plus WAY more. The game engine and the settings screen have both been rebuilt. The game runs much smoother, supports landscape and large screens, and adds a long list of new features, weather, modes and options. With default settings, the core gameplay still feels like the original.

Installing: If the app will not install, uninstall the previous version and try again. Uninstalling deletes your settings and high score, so export your settings first (Settings › Presets › Export to file) and import them afterward.

✨ Highlights

• New rendering engine with much better performance and steady frame rates on 60, 90, 120 and 144 Hz screens
• Full Android 17 support: landscape, tablets, foldables and resizable windows
• Weather: rain, thunderstorms with lightning, and snow
• Dynamic day and night cycle
• New modes: jetpack, drunk mode, autopilot and extra lives
• Golden pipes, real motion blur and screen shake
• Classic feel: a new preset that recreates the physics of the original 2013 Android Flappy Bird (v1.3)
• Redesigned settings built from scratch with Material 3 Expressive
• Live preview that plays by itself and shows every change as you make it
• Saved setups, plus export, import and sharing of your settings
• Medal overhaul with a new shine animation
• Dozens of new options, plus a new Advanced tab for fine-tuning physics

🎮 Gameplay

• Hitting the top of the screen no longer ends the run, matching the original game
• Extra lives: survive up to 9 hits per round, with a short blinking safety window after each one
• Autopilot: the bird flies itself. It handles jetpack, drunk mode, upside down, reverse pipes and moving pipes
• Pause button during play, plus an option to pause automatically when you leave the app
• Difficulty ramp: pipes speed up and gaps shrink as your score climbs, with adjustable limits
• Custom medal scores for bronze, silver, gold and platinum
• Reset your high score on its own, without touching anything else

🚀 New Modes

• Jetpack: hold the screen to fly and let go to fall
• Drunk mode: the bird sways from side to side, with adjustable strength
• Golden pipes: rare shiny pipes worth bonus points, with adjustable chance and bonus

⛈️ Weather and World

• New weather options: rain, thunderstorm and snow, each with its own sound and visual effects
• Dynamic day and night cycle that slowly fades between day and night, with an adjustable cycle length
• Screen shake turns on automatically when you pick thunderstorm
• Thunderstorm lightning reworked:
  • Lightning strikes the bird at set scores (11, 34, 79 and 210 by default, fully customizable)
  • A mega strike at a score of your choice (350 by default)
  • The bird gives off smoke after being struck
  • Pipes show electrical interference after strikes late in the game

🏅 Medals

• Medals are now awarded correctly at each milestone
• Fixed medal positioning on the score panel
• Added a shine twinkle animation to all medals
• Medal scores can now be customized

🐤 Classic Feel (Original 1.3 Physics)

The old experimental FB v1.3 Mode toggle has been replaced with a working Classic feel preset, built to match the original Android game step by step. One tap sets:

• Physics fixed at 60 steps per second
• Original gravity, flap strength and maximum fall speed
• Whole-pixel movement, just like the original
• Original pipe gap, spacing, speed and gap heights
• Original square hitbox and scoring moment
• Original tilt: the bird snaps nose-up on a flap and swings nose-down as it falls
• No flapping while the bird is above the screen, and no invisible ceiling
• Static sky, original bird position and starting height
• Sharp, one-second white crash flash with no screen shake

The row shows Active while your settings match the preset. Sound, vibration, volume, pause and debug options are kept as you set them, and the change can be undone.

🎨 Visuals and Effects

• New rendering engine for sharper, cleaner graphics
• Fixed graphical artifacts on Google Pixel (Tensor) devices
• Real motion blur: moving objects smear like they would on a camera, with adjustable strength
• Screen shake on crashes and thunder, with adjustable strength
• Crash flash: choose its color (white, red, yellow or black), brightness, length and fade
• Bird tint: shift the bird's color around the color wheel
• New settings icon on the main screen
• Optional FPS counter
• Optional hitbox outlines for the bird and the pipes

⚡ Performance

• Maintains a full 120 fps on 120 Hz screens and 60 fps on 60 Hz screens
• Glows and blurs no longer use expensive blur filters
• Rain is drawn in a single batch instead of one line at a time
• Particles (sparks, smoke, trail) are reused instead of created during play
• Color filters for rainbow bird, tint and pipe colors are cached instead of rebuilt every frame
• Sprites are scaled once per screen size instead of every frame
• Fixed a memory leak when rotating the screen
• All timers run on the game's own clock, so animations stay correct after pauses or slow frames
• Long frames are capped so a stutter can no longer send the bird through a pipe
• Core library dependencies updated

📱 Android 17, Landscape and Large Screens

• Full landscape support with no stretching or scaling problems
• Works on tablets, foldables, Chromebooks and in split-screen and freeform windows
• Re-lays out on rotation or resize without restarting the round
• Respects status bars, navigation bars and camera cutouts on every side
• Removed the old aspect ratio warning, since every screen shape is supported now
• Bird, pipes and spacing keep the same proportions on every screen
• On wide screens, the settings preview and options sit side by side

⚙️ Settings

Redesign

Live Preview

• The preview is now a mini version of the game that plays by itself and flies through real pipes
• Uses the same physics as the game, so it behaves exactly like the real thing
• Shows bird color, tint, rainbow, trail, ghost, size, pipes, weather, day and night, golden pipes, lives, pause button, upside down, reverse pipes and more
• Short demos play for screen shake, dimming, hitboxes, lightning, mega strike, moving pipes and the crash flash
• Moving pipes and the difficulty ramp are shown as short samples, since they normally start at high scores
• Moved to its own card, beside the settings on wide screens
• Stops running when hidden to save battery

Presets, Backup and Sharing

• Three save slots that show when each one was saved
• Randomize skips personal options like sound, vibration, volume and pause
