Do you see the little ? button on the bottom-right? Click on it, then move your mouse around the launcher.
I also doubt that I'll remake Carnival to fit all 9 zones. It would have to be careful planning, and it would be too long. Probably more than a minute to finish one lap. And yes, 2 more characters mean Wave and Storm. There's tons of Speed characters, so we need more flight and power characters.
For Ground the "Hog" mistake, I'll fix it once I release a small patch. But since there's no Master Server, there's no hurry.
And until the MS comes back up, I'll take a break from this project to help out with another project here. When it's up, the patch will contain that spelling fix, Turtle Man's fixed code, probably Sky Road and Babylon Guardian, and something cool for Time Attack that I'm not going to say, since I might not get it working right.
