I was once an amateur game developer turned pro (Schell Games, EA, Zynga, PlayStation), then retired from the industry to do my own thing. I'm the creator of the Adventure Game Studio Tween Module, which is used in many indie adventure games.
I'm starting a small game developer/publishing and teaching a course, Game User Interface and Level Design, at Harrisburg University.
(I need to post my old games here or make new ones!)
