I haven't quite gotten SBZ2 finished today as I had hoped. SBZ2 has three obstacles to be overcome, the first of which is the rotating disc here. The object itself is very simple, but it's exposed a problem in the physics where Sonic has difficulty sticking to outer curves, which is why I fall off here. Besides that, there's the elevator, which will probably be mostly easy, and then the fact that SBZ2 is a vertically looping level. I've already done a looping level with LZ3, but it's a real hassle to do manually. Since I want to be able to easily make looping levels for Redux Mode, I'm going to write a script that can just do the work for me when it comes to splitting the level in half and making the appropriate adjustments for all the objects and enemies.
