Also there are a few bugs with this I have noticed while using the editor, which are actually pretty big and I recommend you fix these ASAP:
1 - The music bar in the editor doesn't properly change speed on a speed portal! (Or at least not noticeably)
NVM ABOUT THE ABOVE! IT WORKS AS INTENDED! ITS JUST HARD TO NOTICE A CHANGE IN THE MUSIC BAR'S SPEED BUT IT WORKS AS INTENDED.
2 - If you use an upside down pad or a gamemode cube while upside down with the 3D ball thing, you'll see it doesn't really act as if it was upside down other than changing the gravity. Pads work as if the player had normal gravity, and changing gamemodes while the ball is upside down makes gravity back to normal.
