Approach

How I work

Small team, real players, short loops. Evidence decides what deserves production time.

  1. 01

    Diagnose with data

    Progression funnels, gameplay KPIs and retention data show where players stop. I separate transition problems from gameplay problems before deciding what to fix.

  2. 02

    Iterate fast

    About 12 FTUE market-test iterations on Lucky Clash, across onboarding, early rewards, stage pacing, storytelling and presentation.

  3. 03

    Validate early

    Lightweight HTML5 prototypes and 500-player test runs compared gameplay directions before committing production to one core.

  4. 04

    Build with AI tools

    I use AI tools for fast prototyping, development and deployment, so more ideas reach real players sooner.

About

Game designer who builds what he designs

I'm a game designer and Unity developer with 4+ years of hands-on mobile game development, from system ideation and rapid prototyping to Unity/C# implementation and iteration.

As co-founder and sole game designer at From Beyond Game Studio, I lead gameplay and systems design for Lucky Clash, an asynchronous PvP auto-battler with grid-based combat and strategic team composition. I specialize in combat, character abilities, progression, game balancing and asynchronous PvP, and I use gameplay analytics, KPIs and market testing to guide decisions that improve engagement and retention.
