Beyond the Controller

I believe game design is the highest form of interactive empathy. My process involves deep technical exploration to ensure that the barrier to play is as low as possible, while the emotional payoff remains high.

Games are more than entertainment; they are a medium for connection. My goal is to build games that stay with players long after they've put the controller down.
