Here's another room I forgot about.
>Room gets darker over time
>All the NPC's (except Ye Olde Sprout) change between different Headspace NPC Sprites
>Eventually they'll freeze on one sprite
>Turn into the intangible shadowy forms of the minor Something's
>Ye Olde Sprout simply says "You killed me..."
Spooky. There's dev text in the language files, and completely unused dialogue by a non-existent Lost Soul character that says that Headspace residents that stay in Black Space for too long become Something else. I guess this is an example of how it happens. Which is also implied to be what happened to Abbi's form. I wonder if Ye Olde Sprout's dialogue implies the enemies that we defeat and fade away are actually being sent to Black Space. Every enemy we kill is doomed to this fate. Quite dark, if so.
The 2019 Build implies a different origin for the minor Something's. That they're conglomerations of the little blob things which are Dream Basil's that died in Black Space. It also matches up with what they say during battle. This definitely seems to not be official anymore, but still an interesting bit of history.
