A while ago, I started work on this 3D level in Sonic GDK. It was just for fun, and I started it because I was a little tired of Incursion at the time. I recently opened it up and worked on it a little more, and you can see the level itself below. It's the first level of a hypothetical "cartoony" Sonic game. I don't know when, or even if I finish it and release it, but I thought you might like to see it.
