Non Stage

Non-Stage mode is a Game Mode that's somewhat of a cross between Hubworld Mode and Normal Stage Mode.

Non-Stages have the following properties:

• No events
• No "AlreadyVisited" flag is set
• No Hubworld Scene Objects
• Collected Starbits and Coins are placed in the counters that are used in the hubworld

Why would anyone use this?

It lets you just have an open area to run around in since most normal stage things aren't happening, and most hubworld things aren't happening either.
Which is perfect for levels where you just want like, a cutscene to play, or for use in a prologue/credits level. (The Prologue and Credits are what the vanilla game used this state for.)
