About Left Jun

Current Positioning

I am interested in game project-management and AI-application work that requires both development context and cross-discipline delivery. I can discuss task boundaries with design, programming, art, QA, and platform-release contributors while owning requirement breakdown, owner alignment, version integration, risk follow-up, and delivery.

This positioning comes from work rather than a job title. I have independently built Unity games and pixel art, led cross-university game-jam teams, and coordinated a 14-person research group. Engineering experience helps me identify dependencies and testing risk, while independent-game work keeps scope, completion quality, and public release concrete.

Guanghe Campus Co-creation Program

AI-Assisted Game Project Management

Using my own notes and project experience, I completed a 48-hour takeover SOP, three conflict decisions, a launch review, and a three-month roadmap, receiving an S grade. This was a simulated commercial assignment rather than live-project employment. The Codex risk-monitoring section is a proposed workflow, not a production deployment.

User Research on AI Game-Creation Tools

I coordinated a 14-person team and owned research alignment, sample definitions, the H5 product and backend flow, report integration, and the final presentation. The study exported 117 records, retained 115 usable responses, used 69 university-student samples as the primary analysis scope, and completed five interviews. Public material includes only aggregate results and methodological limits, not the backend, raw responses, or transcripts.

Action-Game Combat and IP Gameplay Translation

I organized a methodology covering action PVP, resource exchange, attack-defense transitions, balance, long-term operation, and IP behavior translation. The public result retains the completed first three chapters. A specific character answer that lacked sufficient source review and gameplay validation is not presented as final work.

Emotion Mask: From Prototype to Release Preparation

Emotion Mask began as a solo 48-hour Global Game Jam prototype, was later published on TapTap with a 9.4 rating, and reached nearly one hundred in-person plays at the Shuguang Youji roadshow in Chengdu. I am continuing work on character 3C, content, controller adaptation, store assets, and review feedback. Both the main game and a standalone demo have been submitted for Steam review.

I drew the pixel characters and animation frames myself. The background music used AI-assisted generation, after which I selected, adjusted, and integrated the material. Cloud saves, controller support, and Workshop work are described according to the distinction between local implementation, submitted content, and production Steam verification.

Project Management and Collaboration

• Confirm the goal, user, and non-removable core experience before breaking down tasks, owners, dependencies, and acceptance conditions.
• Reduce non-core scope in time-boxed work so the playable loop, test milestone, and delivery remain protected.
• Use AI for structure, implementation support, checks, and material processing while retaining human constraints, testing, selection, and responsibility.
• Keep data, feature state, and contribution boundaries clear instead of presenting plans, local implementations, or team outcomes as publicly validated individual results.

Technical Background

• Unity / C#: character control, state machines, level interaction, UI, saves, tooling, builds, and release work.
• Unreal Engine 5: Blueprint, Replication, Listen Server, UMG, basic AI, and multiplayer gameplay flow.
• C / C++ and Qt: object-oriented design, local desktop applications, JSON storage, and build scripts.
• STM32: sensors, wireless communication, servo and motor control, and hardware-software integration.
• Web: Astro, Next.js, responsive interfaces, content systems, and static-site deployment.

At the Sichuan University Water Star Model Boat Competition (Spring 2026), I entered as the only solo team, independently completed the STM32 controller, onboard receiver, PCB, fabrication, and full-system integration, and placed 9th among 72 professional-division teams. It remains concrete evidence of hands-on dependency management, testing, and delivery across hardware and software.

These skills are the basis for understanding development collaboration and solving implementation problems directly. I continue writing code, designing gameplay, drawing pixel animation, and maintaining personal products rather than rewriting technical work as process management alone.

Current Focus

I am continuing Steam release preparation for Emotion Mask, publishing sanitized Guanghe study material, and strengthening UE5 multiplayer, gameplay engineering, and AI-assisted production workflows. This site remains the long-term Left Jun / Limenauts project archive, recording what is complete, who owned it, and what still needs validation.
