Cover image for Mystery of Mount Puma (Misterio
Mystery of Mount Puma (Misterio en la Montaña Puma) Mystery of Mount Puma is a 2D Narrative Adventure prototype where players take on the role of a reporter investigating local myths about strange puma sightings on a legendary mountain. This project focuses on choice-driven gameplay, where player decisions directly impact the narrative and lead to multiple outcomes. Key Technical & Design Contributions: Branching Narrative System: Engineered a decision-making framework in C# that tracks player choices and triggers different story branches and events. Dialogue & Interaction Logic: Developed an interactive dialogue system designed to handle complex narrative flows and character interactions. 2D Environment Design: Created a cohesive visual experience using Unity's 2D tools, focusing on atmosphere and level progression to support the investigation-based gameplay. Cultural Storytelling: Integrated local folklore into the game’s core loop, translating traditional myths into engaging interactive mechanics. Current Status: The project serves as a functional prototype showcasing my ability to build narrative-intensive systems and manage the logical complexity of player-driven stories.

Cover image for Investigación Macabra – Metro de
Investigación Macabra – Metro de las Sombras Investigación Macabra is a 3D Survival Horror Shooter prototype set in a dark, reimagined version of the abandoned subway stations in Santiago, Chile. The game follows a detective investigating mysterious disappearances, only to encounter supernatural entities hidden in the depths of the city. Key Technical & Design Contributions: Systems Programming: Developed the core survival horror mechanics, including a first-person shooter (FPS) system, inventory management, and interaction logic. Environmental Storytelling: Implemented a narrative system where the plot is revealed through collectible journal entries and environmental cues, creating a deep sense of immersion. Level & Atmospheric Design: Engineered a claustrophobic and tense level layout, utilizing dynamic lighting and sound triggers to enhance the horror experience. Collaborative Development: Acted as the Lead Programmer and Designer, collaborating closely with a dedicated 3D artist to integrate custom assets and ensure a cohesive visual and technical experience. Current Status: The project serves as a highly atmospheric technical demo, showcasing my ability to build narrative-driven experiences and solid 3D combat systems within Unity.

Cover image for Immersive VR Industrial Safety Training Simulator in Unity
VR Industrial Safety Simulator This VR Industrial Simulator was developed to provide a safe and immersive environment for technical training and safety procedures. Using Unity and the XR Interaction Toolkit, I built a functional prototype designed to replicate real-world industrial challenges and safety protocols. Key Technical Implementations: Physics-Based Interactions: Developed a precise grabbing and tool-handling system using C# to ensure realistic feedback during procedures. Procedural Logic: Implemented a State Machine (FSM) to manage step-by-step safety sequences, ensuring that users follow the correct protocols to progress. Collision & Trigger Systems: Engineered a robust detection system for industrial equipment, preventing "ghosting" and ensuring accurate object placement. Current Status: The project serves as a functional technical demo, showcasing my ability to translate complex real-world workflows into intuitive virtual experiences. It is currently optimized for PC-VR and standalone headsets.

Last Bastion
Project Description: Last Bastion Last Bastion is a strategic Tower Defense game currently in active development for an upcoming commercial release. The core gameplay challenges players to defend a town against increasingly difficult waves of enemies by strategically managing gold to build and upgrade defensive structures. Key Features & Technical Implementation: Strategic Economy: Developed a balanced gold-based system for building and upgrading towers to ensure a challenging survival experience. Optimized Systems: Implemented Object Pooling for enemies and projectiles to maintain high performance during intense combat. Modular Architecture: Used ScriptableObjects to efficiently manage tower stats and enemy types, allowing for rapid balancing and content iteration. Current Status: The project is in the final stages of development. While currently utilizing placeholders for art, I am focused on finalizing the remaining level designs and polishing the core game loop for its official store launch.
