Is it possible for SMBX?

[YoshiGo99]

I was wondering, is there a way to make SMBX able to have a dark level with a light surrounding the player like some of the Cave levels in NSMBW and NSMBU? Kind of like this

Spoiler: show

Also is there a way to also have Snake Blocks? The ones that appeared in Larry's Castle in SMW and the ones in Bowser's Galaxy Generator of SMG2?

Chad's CC7 level, Magical Malice Castle, had fully-working authentic Snake Blocks, but to do it, he used a lot of complicated-looking event chains which can waste a lot of space - he assigned each Snake Block to its own layer and layers keep disappearing and reappearing in different spots to give the illusion it's moving. In its place, though, an invisible block appears so the player can walk on it.

As for the dark sections, they're made using foreground BGOs or artificially-foregrounded NPCs set not to harm the player, so they can cover up everything including the player. The lighter sections are made using a BGO.
