Buildbox

The Challenge
Buildbox empowers creators to build video games without code. But during a two-week UX audit, I uncovered major friction for new users:
- Onboarding was passive and disconnected from hands-on creation.
- Users lacked visibility into how the platform worked without digging into documentation.
- The creation process lacked logical flow and guidance, especially for beginners.
- Returning users had limited pathways to re-engage quickly or discover new tools.
My Role
As senior product designer, I led the audit and user research phase, driving both qualitative and quantitative methods to uncover user pain points and product opportunities.
Working alongside a product strategist and another product designer, I helped shape the product direction and executed key design contributions across the entire experience:
- Led all foundational research, including user interviews, testing, heuristic evaluations, and data synthesis
- Conceptualized the onboarding experience, bridging guidance with creativity
- Designed the BB Hub and floating window system, enabling flexible, power-user workflows
- Collaborated on the creation and rollout of the Graphite Design System, improving consistency and scalability
- Provided art direction for illustrations and 3D modelling, ensuring a cohesive visual tone across onboarding and product surfaces
The Research
To ensure our solutions addressed real user pain points, we conducted a multi-method research sprint
Methods Used
- Heuristic Evaluation: Identified critical usability issues across the dashboard and editor flows.
- User Interviews: Gathered insights from both new and legacy users to understand behaviour patterns and unmet needs.
- Observational Testing: Watched first-time users attempt to create a game, noting points of hesitation and confusion. Similarly, we observed how legacy users found workarounds to power actions.
- User Testing: Validated proposed changes to the Home screen, game creation tools and flows, and BB Hub interaction model with early-stage prototypes.
User Persona
Meet our core persona: a new, ambitious creator who wants to focus on building, not troubleshooting.

Key Audit Insights
Visualized in a system map (see image), the audit revealed:
- A fragmented user journey from installation to project creation
- Onboarding that didn’t onboard — it didn’t support hands-on learning or create momentum
- A lack of contextual guidance, forcing users to exit the platform and read documentation
- Redundant paths and unclear progression, especially for users starting from scratch
This foundational research allowed us to align teams around the same problem space and build toward focused, measurable improvements.

A Unified Launchpad for All Users
We redesigned the Buildbox Home screen and interaction model to support both first-time creators and advanced users—with guidance, speed, and clarity.
For First-Time Users
- Interactive “Create Your First Game” tutorial fosters learning by doing
- Progress indicators help users re-enter with confidence
- In-product guidance replaces documentation dependency
For Returning and Power Users
- Quick project access via “Open Latest” and recent history
- Familiar layout, now optimized for speed and clarity
- Surface-level achievements and published games to promote engagement and motivation


BB Hub and Floating Window System.
I introduced the BB Hub and a flexible floating window architecture, enabling:
- A centralized place to access tools, settings, and assets
- Customizable layouts for advanced workflows
- A scalable system that evolved into the foundation for future feature releases
These interaction models gave users creative control without adding complexity—especially for power users managing large game scenes.

Graphite Design System
To unify the platform visually and structurally, we created the Graphite Design System. It brought:
- Visual consistency and component reuse across the product
- Faster handoff between design and development
- A design-driven mindset within the Buildbox team, influencing how features were scoped and evaluated

The Outcome
These explorations transformed Buildbox from a fragmented product into a cohesive, creator-first platform.
After running the revamped platform prototype user testing:
- New users get started faster, with less frustration
- Returning users started build with more speed and flexibility
- The development team is now equipped with scalable UI systems and a clear design language
| The result: a launch experience that reflects what Buildbox stands for: enabling creators to build, explore, and ship ideas without barriers.
