Build 39 laid the groundwork for everything that followed, including the massive animations overhaul in Build 41. It turned the map into a connected world where the distance between Muldraugh and West Point could be traversed in minutes rather than days.
| Feature | Build 39 | Build 41 | |---------|----------|----------| | Animations | 2D sprites | Full 3D skeletal | | Zombie movement | Standard walk only | Crawling, lunging over fences, clumping | | Combat | Click-to-hit, no targeting | Aim outline, melee swing arcs | | Multiplayer | Stable (no vehicles sync issues) | Fully synced + split-screen | | Map | Smaller (no Louisville) | Full map including Louisville | | Mods | Manual install | Steam Workshop integrated | | Performance | Excellent on potato PCs | Heavier (needs dedicated GPU for smooth 60 FPS) | | Metalworking | No | Yes (melt, forge, weld) | | Fitness/Strength | No exercise skill gain | Exercise system |
Build 41 is superior in every way except hardware requirements. Use Build 39 only for low-end PCs (4 GB RAM, no GPU) or to run legacy mods.

Hyena Rider Assistant (HRA) is an auxiliary e-bike app for end-users, offering effortless management of e-bikes' system anytime, anywhere. It provides seamless monitoring and control capabilities with main functions including: e-bike pairing, route recording, riding data, part firmware update and maintenance reminder.
Although the e-bike can be used independently, we hope to increase user stickiness and product value through the app.
When I took over the project, the product was in the late MVP stage, but there were significant UX issues and technical debt. My goal was to fix issues, stabilize the product, and drive cross-departmental collaboration in preparation for the next round of growth.
// I was the designer who redesigned the HRA 1.0 to version 2.0.
1. Inheriting Legacy Gaps
The app was already under development but lacked key UX refinements and had unresolved technical debt. My role began with a comprehensive review of the product, identifying issues across functionality, design, and stability, and leading efforts to stabilize the app for continued iteration.
2. Cross-Department Communication
The development involved cross-functional teams: hardware, firmware, software, marketing, and after-sales teams. Each team had unique priorities, which often led to misalignment. I became the key facilitator, bridging technical and business goals while ensuring feedback from users and markets was continuously looped back into development priorities.

3. Hardware-Software Integration:
Unlike pure digital products, HRA required an in-depth understanding of how users interact with physical e-bikes. Design decisions couldn’t be made in isolation from firmware behaviors or riding context. This complexity required me to approach UX design not just as interface work, but as a bridge between rider behavior, hardware reality, and app logic.

4. Driving Value in a Non-Essential App
Because the e-bike didn’t require the app to function, a major challenge was defining and communicating the app’s unique value proposition. We focused on enhancing perceived value by developing features like personalized ride data, health metrics, and predictive maintenance reminders to make the app feel indispensable rather than optional.

5. Through Data to Justify Product Decisions
To prioritize improvements, I worked on identifying pain points using usage data and support feedback. I translated these into persuasive cases backed by data to ensure resource investment in key user experience problems, particularly those affecting retention.
