⌨️ Controls

  • SPACE, ↑ or W flap
  • Clicking or tapping the sky flaps too
  • P pause  •  R new game
  • Your first flap starts the game — no need to press start.
  • 🎮 Xbox controller? Just plug it in or pair it — the stick and D-pad are the arrow keys, A is SPACE, Menu pauses and View starts again

🎯 How to play

  • The bird falls all by itself. Flapping is the only thing you control.
  • Fly through the gap in each pipe.
  • Touching a pipe, the ground or the ceiling ends the run.
  • Short taps beat long ones — flap little and often.

🏆 Scoring

  • One point per pipe you get through.
  • Every 5 pipes the game speeds up a little, all the way to level 15.
  • Ten pipes is a good run. Twenty is showing off.
  • Tip: aim for the middle of the gap, not the bottom of it.

🧑‍💻 This whole game is Python

There is almost no JavaScript on this page. The browser downloaded Pyodide — a complete Python interpreter compiled to WebAssembly — and then ran the .py files in funtime/pylib/. Python does the rules, the maths and the drawing.

File What it does Good functions to try re-writing
pylib/flappy_rules.py The rules: gravity, pipes, crashes apply_gravity, flap, move_pipes, is_crashed
pylib/flappy_draw.py Painting the sky — Python calling the canvas draw_pipe, draw_bird, render_game
pylib/flappy_web.py The glue: the keyboard, the taps, the loop do_action, on_board_press, frame

🔍 Compare the two versions. Open lib/flappy-rules.js and pylib/flappy_rules.py side by side — same ideas, two languages.

🛠️ Build it yourself: Build Flappy in Python walks you through the functions one at a time.

⚠️ If the game never starts: the page has to read its .py files, which a browser will not do for a page opened straight off your disk. Use the live site, or run python3 -m http.server in the project folder.
