Marballed is a four player game where three players are paint drops competing to collect three points and win, and the fourth player is a mayhem-causing marble.

Stephen was the Creative Director for Marballed, overseeing the design, visual style and overall feeling for the game. It was developed as part of the capstone unit for Bachelor of Arts (in Games & Interactivity) at Swinburne University.

The initial concept had a more science-fiction style but after playtesting and seeing that children and families were really enjoying the gameplay, the theme was changed to a more colourful, arts and crafts style. Marballed was shown at PAX Aus 2017 as part of the Swinburne booth.
