Lead Game Designer & Product Owner

I build games
players come
back to.

From the first playable to the next live event. I connect game design, product thinking and player psychology to build experiences that grow.

Ten Square Games
01 / Selected work

Built for players.
Grounded in results.

A closer look at the systems, experiences and live games I’ve helped bring to life.

02 / How I work

Player instinct.
Product discipline.

Good systems connect what players want to do with what makes a game sustainable. I work across that entire journey.

01

Understand the player

Use psychology, research, funnels and feedback to understand motivation, friction and the reasons people return.

02

Design the whole loop

Connect core gameplay with progression, social systems, economy and UX. Make each feature fit the wider game.

03

Own the delivery

Take features from concept and UX through implementation, release and iteration. Collaborate across disciplines or build hands-on with AI tools.

04

Learn from the live game

Use A/B tests, player behavior and LiveOps results to refine events, offers and systems after launch.

03 / A little about me

Designer.
Product thinker.
Hands-on builder.

I’m Mateusz, a game designer based in Wrocław, Poland. Over 6+ years in F2P games, I’ve moved from running live events to owning systems, product decisions and complete game development.

My background in psychology and UX design shapes how I approach motivation and usability. I combine that with hands-on implementation, analytical thinking and a willingness to test ideas early.
