I saw an unfinished fragment of a boss fight from deltarune. The whole battle was tea themed, Kris was in a teacup like in ch2 but it was just falling down into the black void (while Kris for some reason being in his overworld idle animation), there was no background. The enemy was a robot but like someone was controlling it. I'm pretty sure I saw Noelle and someone else fighting this guy with us but I'm not sure: in one fragment it was Kris alone and in other one with some dudes.

Though all I remember thinking of it in the dream was "damn I wonder what engine this is. Probably clickteam."

I had to share it or I'd go insane. This is the first time I ever saw deltarune in my dream and could somewhat describe it.
