Just wanted to say real quick that I'd personally downvote the theme: "Games that shouldn't be in first person done in first person"

It basically takes the idea of doing any kind of 2D game out of the picture, making things harder for those of us with less experience with 3D, or using an engine that flat out doesn't support it.

It's a neat idea for a project. But as a game jam theme, I just don't think that it fits. Especially with the huge amount of people with varying skill levels, using a huge variety of tools.
