🎮 Game Glitch Investigator: The Impossible Guesser

🚨 The Situation

You asked an AI to build a simple "Number Guessing Game" using Streamlit. It wrote the code, ran away, and now the game is unplayable.

• You can't win.
• The hints lie to you.
• The secret number seems to have commitment issues.

🛠️ Setup

1. Install dependencies: pip install -r requirements.txt
2. Run the broken app: python -m streamlit run app.py

🕵️‍♂️ Your Mission

1. Play the game. Open the "Developer Debug Info" tab in the app to see the secret number. Try to win.
2. Find the State Bug. Why does the secret number change every time you click "Submit"? Ask ChatGPT: "How do I keep a variable from resetting in Streamlit when I click a button?"
3. Fix the Logic. The hints ("Higher/Lower") are wrong. Fix them.
4. Refactor & Test. - Move the logic into logic_utils.py.
   • Run pytest in your terminal.
   • Keep fixing until all tests pass!

Game Purpose

Glitchy Guesser is a number guessing game built with Streamlit. The player selects a difficulty (Easy, Normal, or Hard), which sets the secret number's range and the number of allowed attempts. Each guess receives a hint — "Go HIGHER!" or "Go LOWER!" — to guide the player toward the secret number. The goal is to guess correctly before running out of attempts, with a score that decreases the more guesses it takes.

Bugs Found

#	Bug	Location
1	Hints were backwards — "Go HIGHER!" shown when guess was too high	check_guess in app.py
2	New Game button did nothing after a win or loss	New game handler in app.py
3	Submit button required two clicks to register	st.text_input + st.button in app.py
4	Attempts left counter started at 7 instead of 8 on Normal	Session state init in app.py
5	Normal and Hard difficulty ranges were swapped	get_range_for_difficulty in app.py
6	New Game always picked a secret from 1–100 regardless of difficulty	New game handler in app.py
7	Switching difficulty didn't reset the game state	Session state management in app.py

Fixes Applied

1. Swapped hint messages in check_guess — paired "Go LOWER!" with guess > secret and "Go HIGHER!" with guess < secret.
2. Added st.session_state.status = "playing" (and history reset) to the New Game handler so the game unblocks after a win or loss.
3. Wrapped text input and submit button in st.form so both are submitted atomically in a single rerun, eliminating the double-click issue.
4. Changed st.session_state.attempts init from 1 to 0 so the attempts left display is accurate from the start.
5. Swapped Normal and Hard return values in get_range_for_difficulty — Normal is now 1–50, Hard is 1–100.
6. Replaced hardcoded random.randint(1, 100) in the New Game handler with random.randint(low, high) to respect the selected difficulty.
7. Added difficulty change detection using st.session_state.difficulty — switching difficulty now fully resets the game state.
8. Refactored check_guess into logic_utils.py and added a conftest.py at the project root so pytest can find the module.
9. Fixed existing pytest tests to unpack the (outcome, message) tuple returned by check_guess, and added two new tests specifically targeting the swapped hint message bug.
