I had a really weird one that was kind of a bunch of games and other things mashed together.
So we start out in what seems to be a genocide route, like from Undertale, but with pokemon. Then sans shows up and we get sent to space
I remember there were three girls with me for some reason and they were all in plug suits (it's a thing from neon Genesis evangelion, really good anime btw)
Me and one of them were in white suits, similar to rei, and the other two were in red ones, similar to asuka
One of the red ones suddenly had malice spewing out of her chest for some reason then everyone disappeared and there was some sort of parkour thing
The main thing I remember from that part is this one weird one with two rocks stacked on top of each other in a stone bowl, I had to jump on the rocks, and spin around the bowl on both of them, then I'm on the next platform. For some reason a joystick icon showed up that the bottom of my vision.
After that, sans shows up again with some sort of robot assistant, and we get sent back to earth. And idk why but after that we were all just staring at an eevee.
