loved ones, symbolizing the completion of their arduous journey.

4. Code Structure and Key Features

4.1. Modular Design

The project adheres to a modular programming approach, where the game is divided into self-contained
functions. Each function serves a specific purpose, such as handling an encounter, resetting the game, or
validating input. This structure promotes code clarity, reusability, and ease of debugging.

4.2. Use of Programming Elements

i. Loops:
Loops are utilized to control repetitive gameplay mechanics, validate user inputs, and manage
retry attempts. For example, riddles allow up to three attempts to answer correctly, with the
game terminating upon failure.

ii. Conditional Statements:

Conditional logic determines the flow of the game based on player decisions. For instance:

o Choosing between the Misty River and the Paved Road alters the storyline.

o Encountering the Ancient Guardian leads to different outcomes depending on the

player’s answers.

iii. Functions:
Functions such as startGame(), mistyRiver(), temple(), and gameOver() compartmentalize the
code, ensuring modularity and clarity. For example:
 o The temple() function integrates puzzles, parkour challenges, and a seamless transition
to subsequent encounters.

o The resetGame() function resets global variables, enabling players to restart the game
from scratch.

iv. Global Variables:

Variables like mistyRiverVisited and returnedToFork track game progress, ensuring logical
consistency in gameplay. For instance, revisiting the Misty River after it has been marked as
visited leads to a game-over scenario.

v. Input Validation:
The game employs rigorous input validation to handle unexpected or invalid inputs gracefully.
For example:

o Players are prompted to re-enter valid choices when numeric input is required.

o Non-alphabetic characters in riddle answers are detected and rejected with meaningful
feedback.

vi. Recursion:
Recursive calls are used for restarting the game after a win or a game-over, demonstrating
efficient program control while maintaining the flow of the storyline.

vii. Randomization:
The rand() function ensures a dynamic experience by selecting random riddles or encounters,
increasing replayability.

5. Key Challenges and Solutions

5.1. Managing Game State

 Challenge: Tracking player progress (e.g., locations visited, decisions made) without allowing
unintended repetitions like revisiting the Misty River.

 Solution: Global variables (mistyRiverVisited, returnedToFork) monitor progress, while the

resetGame() function clears these variables to restart the game cleanly.

5.2. Input Validation and Error Handling

 Challenge: Preventing crashes or illogical behavior from invalid inputs such as non-numeric
characters or overly long strings.

 Solution: Loops were used to validate inputs. Numeric inputs required integer checks, while
string inputs were verified with the isValidAnswer() function to accept only alphabetic
characters.

5.3. Logical Consistency and Flow

  Challenge: Maintaining a seamless narrative flow while giving players the freedom to make
decisions.

 Solution: Extensive testing was conducted to identify and eliminate logical inconsistencies. For
instance, revisiting the Misty River correctly triggers a game-over scenario.

5.4. Designing Engaging Challenges

 Challenge: Creating riddles that were stimulating but not overly complex for players.

 Solution: Selected riddles like "What has to be broken before you can use it?" (Answer: Egg) and
validated answers through multiple retry attempts.

5.5. Debugging Complex Scenarios

 Challenge: With numerous branching paths, debugging required meticulous attention to ensure
smooth progression.

 Solution: Edge cases, such as exceeding retry limits or revisiting paths, were addressed through
default behaviors like calling gameOver() or resetting variables.

6. Challenges Faced During Development

The development of the text-based adventure game presented several challenges that required careful
problem-solving and iteration. Below is a deeper exploration of these challenges:

6.1. Game State Management

Challenge:
The game needed to track the player's progress and ensure consistency in gameplay was challenging.
This included preventing revisits to previously completed areas and resetting variables during a game
restart.

Solution:

 Global variables such as mistyRiverVisited and returnedToFork were used to monitor specific
game states. These variables ensured logical consistency and prevented players from revisiting
places unnecessarily.

 The resetGame() function was designed to clear all progress-related variables, ensuring that
every new playthrough began with a clean slate. This avoided issues like residual game states
affecting subsequent plays.

Outcome:
This solution provided a structured way to manage the player's journey and maintain logical consistency
throughout the game.
6.2. Input Validation and Error Handling

Challenge:
Players frequently make errors, such as entering non-numeric characters for numeric prompts or
providing overly long and invalid answers to riddles. Without proper handling, these could cause crashes
or disrupt gameplay.

Solution:

 For numeric inputs, validation loops checked whether the input was an integer. Invalid inputs
triggered error messages and allowed retries.

 For string inputs (e.g., riddle answers), a custom validation function, isValidAnswer(), ensured
only alphabetic characters were accepted. It also prevented excessively long inputs, guiding
players toward meaningful responses.

 Buffers were cleared of invalid characters to ensure smooth execution.

Outcome:
These mechanisms created a robust system that not only prevented crashes but also enhanced the user
experience by providing clear and helpful feedback.

6.3. Logical Flow and Consistency

Challenge:
The game offered dynamic choices, allowing players to make decisions that influenced the storyline.
Maintaining a logical narrative flow while accounting for all possible player actions was complex. Poorly
designed logic could lead to contradictions or unintentionally abrupt endings.

Solution:

 Each function (e.g., mistyRiver(), guardEncounter()) was carefully crafted to handle specific
scenarios and outcomes. Flags like returnedToFork were implemented to ensure a seamless
return to the main storyline after side events.

 Revisit logic was incorporated to block redundant actions, such as revisiting a completed area
like the Misty River, which triggered a specific game-over scenario.

Outcome:
Extensive testing and thoughtful narrative design ensured the storyline remained cohesive and
immersive, with every decision flowing logically into the next.

6.4. Designing Challenges and Puzzles

Challenge:
Creating engaging riddles and puzzles that were neither too easy nor too difficult required a balance
between complexity and accessibility. Additionally, the challenges had to fit organically within the game’s
narrative.

Solution:

 Riddles were carefully selected for their logical appeal and relevance to the storyline. For
example:

o "What has to be broken before you can use it?" (Answer: Egg).

o "I am a five-letter word. I get shorter when you add two letters to me." (Answer: Short).

 Players were given clear instructions on input format (e.g., alphabetic-only answers) and allowed
up to three retry attempts for each puzzle, providing a balance between challenge and fairness.

Outcome:
The puzzles became integral parts of the storyline, adding intellectual engagement while ensuring
players could progress without frustration.

6.5. Debugging Complex Scenarios

Challenge:
With branching narratives and multiple paths, debugging the game was a time-intensive process. Edge
cases, such as revisiting untracked locations or exceeding retry limits, posed risks of disrupting gameplay.

Solution:

 Comprehensive testing was conducted for each scenario individually and in combination with
others. This helped identify and resolve edge cases, such as:

o Players exhausting retry attempts for puzzles or making invalid choices repeatedly.

o Revisiting paths that weren’t properly blocked.

 Default behaviors were established for unresolved scenarios, such as triggering gameOver()
when players exceeded their retry limits.

Outcome:
The game achieved a stable and polished flow, even under extreme or unexpected player actions.

7. Immersive Gameplay Features
