These are instructions for thehappytroll to implement this disaster. You can read if you're not him, but it probably won't help you unless you plan to add this yourself. The background and stage is custom to show the warped effect. Put this into the map sprite, foreground sprites if needed, and the background. The black hole just needs to be linked up to the player death script and the disaster script, as far as I'm aware. The disaster is supposed to work like this: Once the Fractured Wormhole appears, it will grow and shrink. Adjust the size caps to your liking, but make sure that the player can avoid touching the Black Hole at it's maximum size when hugging both the left AND right walls on EVERY MAP.
Thanks to thehappytroll for making this amazing game, and to myself for editing that ear-destroying sound effect. Hope ya liked it XD
