The Mansion - PvP Asymmetrical Console Game

Time: Sep 2023 - Dec 2023
Roles: Game Designer, Programmer
Tools: Unity

The Mansion is a two-player asymmetrical PvP game developed over a semester by a five-person cross-disciplinary team. One player controls a little girl in an action-adventure style, while the other plays as a ghost leader using strategy to control spirits. Built in two-week sprints, the game explores gameplay using controller and mouse/keyboard.

Main Contribution:

Level & Narrative Design: Designed the mansion level layout and puzzle flow, incorporating Chinese architecture and folklore-inspired monster encounters. Wrote the overarching story and objectives, enriching gameplay with emotional stakes and traditional themes.

Gameplay Programming: Implemented core player and enemy action states (attack, dodge, death, hurt, idle) using C# in Unity. Built locomotion systems for both third-person and god-view perspectives, managing character speed, force, and navigation. Developed gameplay modifiers for animation, hitbox/hurtbox detection, stamina, and invincibility mechanics.

System Architecture: Created robust systems for combat state machines, enemy AI, player tracking, and status management. Developed UI systems including health/stamina displays, menus, and input-based UI alignment.

Production & Prototyping: Led integration of design, programming, audio, and art assets across platforms. Rapidly prototyped and iterated level and gameplay systems using team feedback and testing.

Narrative Design

You are a girl who tries to retrieve your dead grandma's memory pieces (three objects) by venturing into the haunted ancient Chinese mansion; and you are a monster residing in the mansion trying to kill the girl who intrudes on your territory...
