Game Design, UI Design,
If time permits, I work on digital board games. It's fun to invent rules and test their effects. It also helps me refine my developer capability.
Board games on devices such as Tablet, Phone and PC have the great advantage that there is no need to care for game material or count anything and missing players can be replaced by computer players.
Two games are currently available as apps in the Microsoft Store. A web browser game is currently in the alpha phase.
