Y'know. This is one of those 4AM thonks.
It is worth to post this despite the fact it's a fangame? Dunno. SOMEONE will probably find it interesting? If someone already posted this, I blame YT search.

By the way, I also found that you can enable a test mode by using the command line argument "-fartchungusamongus". (Yes, really). Lets you play with some debug menus and find an unused soul mode. Fun stuff.

So, yes. Memes.

EDIT: In version 3, the room is not significantly different. There is an extra Ralsei in it, though. The debug mode access cmd argument no longer works, though.
