I'm surprised no ones pointed this out yet because its such a clear reference, but in the chapter 4 snow grave route in the scene where you put the thorn ring on Noelle, the colors change for some reason, and Kris's color palette gets eerily similar to a certain someone's (Chara). Considering this is basically the Deltarune version of the genocide route this HAS to be intentional, i'm not a fan of the third entity theory and I think this is more of a reference, but it's noteworthy. The Snowgrave routes goal is likely to transfer us, the player into Noelle so we can use her powerful ice magic, or perhaps someone else? I doubt its Chara being transferred though.
its a small detail but since not a single soul has talked about this I had to
