• Customization: Choose between a Red Car (higher speed) or a Yellow Car (different penalty structure).

• Persistent Leaderboard: Top 10 scores are saved to a file using file I/O operations and sorted via Bubble Sort.

• Sound Effects: Real-time audio feedback for crashes, pickups, and menu clicks.

## Technical Stack

## Setup & Installation

1. Prerequisites: Ensure you have Visual Studio installed with the MASM (Microsoft Macro Assembler) component.
2. Library Configuration:

• Include the Irvine32 library in your project properties.

3. Running:

• Open the .asm file in your IDE.
• Build the solution (Ctrl+Shift+B).
• Run the executable (Ctrl+F5).

## Scoring Logic

Different cars have different "risk/reward" profiles:

• Red Taxi: Faster starting speed, but penalizes hits on other cars more heavily (-3 pts).
• Yellow Taxi: Standard speed, but harsher penalties for hitting static obstacles (-4 pts).
• Universal: Hitting a pedestrian results in a -5 point penalty. Dropping a passenger earns +10 points.
