During development of Marble Explorer I started out as a character designer and quickly began gathering images for what I/we wanted the charter to look like with its tone and feel. However after some initial mock ups for characters I transitioned to become a level designer as this was something I feel much more comfortable doing for a group task. As I transitioned later during development there was a 'problem' of some levels being already being blocked-out and iterated upon. Knowing this and feedback from them I wanted my level to play completely different to the rest, so I came up with the idea of creating a 3 lane course map (Seen in gallery). 

After multiple blockouts and play through with feedback for where traps and abilities should go, I had a finished map with everything we needed inside. It played right, felt good and most importantly 'had not bugs'.
