Unity developer focused on mobile puzzle games

Clear gameplay, reliable systems, and thoughtful execution.

I build puzzle experiences for mobile with an emphasis on readable interaction, consistent logic, and production-ready delivery. My work spans gameplay design, implementation, iteration, and release support.

Project Notes

A short breakdown of the work, not a long list of buzzwords.

Colorful Words: Reveal Puzzle

Puzzle design supported by practical production work.

I contributed to the project from the perspective of both player clarity and delivery discipline: keeping the board readable, validating content, and making sure repeat sessions stayed smooth on mobile.

Contribution
  • Built gameplay flows that keep puzzle states fair, understandable, and finishable.
  • Refined interaction feedback and UI behavior for short, repeatable mobile sessions.
  • Supported retention features such as daily play loops without overwhelming the core rules.
Toolset

Working style

What stays consistent

Readable gameplay, measured iteration, and features that are sturdy enough to survive real production constraints.

Play Lab

A small interactive touch keeps the page lively without making it noisy.

Mini game

Tic-tac-toe

A lightweight break built directly into the portfolio. You play as X, the site responds as O, and the rules stay intentionally simple.

You: 0 Site: 0 Draws: 0

Your turn.

About

I enjoy work that looks simple on the surface because the underlying decisions are doing their job.

My process usually starts with the rule set, then moves into validation, feel, and presentation. I care about whether a feature reads clearly, responds well, and remains maintainable after the first version ships.
