MY PROJECTS

Cheese Panic

Cheese Panic is an asymmetric online multiplayer game developed in Unity, where one Cat competes against a team
of Mice in physics-heavy interactive household environments. I developed core gameplay and multiplayer systems
including Steam lobbies, player roles, host-authoritative interactions, synchronized physics objects, abilities, items,
round flow, shared team lives, escape objectives, and proximity voice chat.
I also contributed heavily to the game design, including player roles, abilities, round structure, objectives, progression,
balancing, interaction design, and the overall gameplay loop.
On the technical side, I worked on network performance optimization, snapshot and player-state synchronization,
multiplayer state management, and reducing latency and desynchronization issues.

Wayflare

Wayflare is a real-time location-based multiplayer strategy game built around real-world map interaction, territory
control, and base building.
I worked on the client-server architecture, multiplayer state management, territory ownership logic, player actions, and
persistent game state.
The project required designing gameplay systems around geographic data and synchronizing shared world state
between multiple players.

Dopamine Pit

Dopamine Pit is a 3D first-person game developed during a game jam around a satirical dopamine-loop concept.
I built interconnected gameplay systems for dopamine, hunger, currency, upgrades, object interactions, an in-game
smartphone, and several mini-games.
The project focused on rapid prototyping and integrating multiple mechanics into a complete playable gameplay loop
under strict time constraints.

Dog Dream

Dog Dream is a stylized 3D narrative game focused on exploration and environmental storytelling from a dog's
perspective.
I was responsible for game design and helped shape the core player experience, gameplay flow, exploration
mechanics, environmental interactions, and camera-driven narrative sequences.
I worked closely on defining how the player moves through the game, interacts with the environment, and experiences
the story through level structure and gameplay rather than dialogue.
