Trade Market:

• Genre: 2D Top-Down Trading Puzzle

• Engine: Unity

• Highlights of the Game:

  • Dynamic Trading System: Developed comprehensive NPC interaction mechanics with desire-based bartering, dynamic trade negotiations, and checkpoint-gated progression through three distinct market levels.

  • Hybrid Gameplay Mechanics: Seamlessly integrated peaceful trading phases with surprise combat encounters, featuring damage systems, cooldown mechanics, and enemy wave management for climactic battles.

  • Fluid Movement System: Implemented precision top-down controls with dash mechanics, strafing capabilities, and smooth character navigation for enhanced player agency in both trading and combat scenarios.

  • Modular Level Architecture: Built tilemap-based market environments with artist-friendly workflows, enabling rapid level iteration and scalable content creation across multiple trading zones.

  • Cinematic Camera System: Integrated Unity Cinemachine with Follow and Confiner components for dynamic camera tracking while maintaining strict boundary constraints for optimal visual experience.

  • Performance-Optimized Systems: Engineered object pooling for trading prompts, market stalls, and enemies to minimize garbage collection overhead during intensive combat sequences.

  • Event-Driven Architecture: Developed decoupled communication system using Observer pattern for trade completion, state transitions, and damage notifications across game systems.

  • Data-Driven Design: Implemented ScriptableObject-based configuration for items, trade relationships, and game states, enabling external content management and rapid balancing iterations.

• Key Takeaways

  • Advanced Architecture: Mastered multiple design patterns (MVC, Factory, Repository, Singleton, State Machine) creating maintainable and scalable 2D game architecture.

  • SOLID Principles Application: Demonstrated expertise in dependency injection, interface segregation, and single responsibility principles for robust, testable codebase development.

  • Performance Engineering: Enhanced skills in coroutine-based timing systems, efficient update loops, and memory management for smooth gameplay during complex interactions.
