Sonic Mania! [ALL THE SPOILERS]

The HBH boss in Studiopolis has two paths between segments. Once you get those rings that's it. It seems random as to which one you run through, though.

In Blue Sphere there are sometimes rings already on the course, but most of them are revealed by "outlining" grids of spheres 9x9 or larger. That will cause all of them to become rings. That's why it's important to save non-ringable spheres for last so you don't miss getting a perfect.

Another tip for the special stages is jumping at corners for tighter turns. This is especially helpful while at mach 2 or 3. Apparently you can even catch the UFOs at mach 1 utilizing jumping well enough. I caught one at mach 2 once.

One of my favorite moments of the game I forgot to mention was seeing Oil Ocean Zone for the first time. While seeing the train in Mirage Saloon I noticed that the tanker car reminded me of Oil Ocean's style, then that ended up being the next zone. I was hyped up thinking "That train was heading to Oil Ocean!"

I am also really surprised that Ice Cap didn't get a remake (or hasn't yet in general). For being such a popular zone it hasn't been getting much love. Aside from freezing in Press Garden Zone I can't even think of any callbacks to it.

Oh, and one more disappointment was the zone transitions. It was said they would return, so I was expecting there would be one for all of them. Instead there were only four or five I think.
