Developer: Video Soft

Video Soft is the developer credit on Mogul Maniac (1983), a slalom skiing game published by Amiga Corporation. It was sold with the Joyboard, a board you stood on and leaned to steer, and it was the only game released for it at the time. You ski nine courses through red and blue gates against the clock. Since the Joyboard was wired like a joystick, the keyboard works fine here.
