My Design Roles

I was the Level Designer and Gameplay Programmer, crafting engaging puzzle maps with innovative mechanics and implementing movable environment features.

Challenges

Designing my first puzzle maps with custom movable elements; programming untested features such as hidden collectibles; and texturing graybox levels without time for post-process lighting passes.

Lessons Learned

I learned that puzzle games demand deep iterative thinking and that misaligned visions among collaborators require clear, continuous communication to preserve cohesive gameplay and art direction.
