Escape Room Designer, Game Consultant & Puzzle Creator
Hi, I’m David Middleton, founder of Rebel Brain. I help production companies, creative agencies, venues and ambitious brands turn creative ideas into fun, intuitive, immersive experiences that captivate their audiences.
Trusted by world-leading brands & IPs.
How I can help you
If you have a great idea but no clear way to turn it into an interactive experience, I help bridge that gap with design, documentation and gameplay, whether it’s for two players or two thousand.
Escape Room Design
When you need a puzzle-driven experience but don’t have in-house gameplay expertise, I design escape rooms that flow smoothly, delight players and support your theme, audience and operational needs.
Immersive Experience Gameplay
When your show or activation needs engaging, interactive moments, I create puzzles, challenges and audience interactions that support your narrative, tell your story and bring your worlds and brands to life.
Outdoor Puzzle Trails & Adventures
When you want to create a puzzle adventure across a city, venue or large indoor space, I design trails and mission-led experiences that feel intuitive, surprising and engaging for groups of any size.
Technical Documentation
When your project needs clarity, structure and clear communication between creative and production teams, I create the game flows, puzzle logic and operational guides that turn complex ideas into clear, production-ready experiences.
Game Consultancy & Concept Development
When you’re stuck on an idea or need a creative partner, I help you shape, sharpen or rescue your concept, from early brainstorming through to fully structured gameplay.
Playtesting, Staff Training & Operational Support
When you need confidence that your experience works as intended and for the audience it was designed for, I test it thoroughly, refine the gameplay and prepare your team so it runs smoothly and reliably.
