MapleStory: Design

A simulator and designer for Maplestory that allows players to design their own characters and try out new Cash Shop items that are available in-game.

We launched Design with the focus of bringing together animators and creators within the community, and strengthening the connection players have with their characters. With the disappearance of BannedStory (due to the owner's passing), this was our first project created solely by request of the MapleStory community.
