I originally got my start in game design with fan made Tabletop Roleplaying Games. This was a fan made game for the popular webtoon 'Tower Of God'.

I helped to create many of the core game systems, interactions between systems as well as creating the character sheet and the programming that went into it. I also handled the planning and collaboration between different design teams on this project.
Although a it is a tabletop game, this project taught me a lot about game design and was the initial spark in my game design journey.
