About David & OutBox Games

I’m an independent game designer and programmer behind OutBox Games – a small studio where I explore game design patterns, build my own tools, and use AI as a creative partner rather than a shortcut.

The OutBox Games Ecosystem

OutBox Games is more than a collection of projects – it’s an ecosystem. I use Actionary for ideas, SpriteGrid and friends for production, and a growing library of games to put everything into practice.

Actionary Tools

Topic Creator, PatternChooser, MechanicVerber, and the PatternDex – tools for structured ideation and thinking in game design patterns.

Production Tools

SpriteGrid and future editors that help me build sprites, levels, and other assets for HTML5 and retro-inspired projects.
