Vow of Offering

(Unity｜2-person)

  • Hitbox/Hurtbox ↔ Camera-shake curve linkage, enhancing hit feedback.

Sisyphus’s Worst Day

(Unity｜30-person)

You are not Sisyphus, but the “hand of fate” constructing the only solution.

  • Behavior Tree (patrol/chase/interact) stabilizes encounter rhythm.

  • “Moving building” mechanic + anti-“cheat path” constraint, offline solution validation.

Cemented Dream

(Unreal｜30-person)

Concrete tower stealth: move/hide/sneak/slide state machine with guard search AI.

Sumo Slam

(Unity 2D｜2-person)

Hitbox + State Machine, making a sumo fight purely about feel.

  • Camera-shake × audio-visual sync, building weight and impact feedback.

Portal
(C++ Remake)

Rebuilding Portal’s spatial rules in minimal form to grasp its engineering core.

  • Collision detection, level switching, and respawn cycle.

Hell Meme
(Unity 2D｜5-person)

A Hold-to-Open key builds readable yet tense elevator pressure.

  • Long-press gate + rhythm sound/vibration escalation creates risk windows.

  • Enemy spawn/evacuation thresholds with “merit” scoring balance tension and success.
