hi, i'm rein !
I am a Game Designer. I focus on Game Systems, gameplay mechanics, progression loops, and scripting with Unreal Engine 5 Blueprints and Unity C#.
​
I worked on 2 AAA projects, 8 game jams, and at least 15+ student projects.
I love making games that are fun and innovative (i.e. the games that people like).
