3d art can take more overhead to produce, but it gives a very different aesthetic than 2d art. We were really lucky to have someone on our team with 3d art experience.

At one point we did play around a little with having the camera turn and fly around when the knight grabs the cup at the end of a level, but the levels are really only build to look good from one perspective, and it would have been hard to make it work well.

Trine is done that way as well. It's surprisingly immersive for a platformer.
