So, I don't know if this was known but, it seems with Tails (and Knuckles if you spin dash up the mini slope and fly to the wall the the left) you can fly over the boss of SSZ1. The only bad thing is it's not much of a skip. You can destroy the machine, hit the Future post (which oddly stops the game timer), hit the speed boosts but, nothing happens... Except you get the sparkling trail effect. It's useless but, I thought it was interestingly weird.

Another thing I have is a question that I've been sitting on. Is it possible when done in a run (game or Time Attack), this could save some kind of time or no?

Side Note: The SSZ1 thing I did in Debug Mode but in a normal game, you'll still get the cutscene that goes into SSZ2.

So, before this patch and of course when PC version was out, there were no glitches.

But, by sheer luck (don't ask why I even tried it) seems there is one skip from console I can confirm is this skip in Studiopolis Act 2.

Now, I'm not a pro glitch finder/executioner but, is it possible the others are in the game as well?
