I Know Its Kinda Dumb - Tumblr Posts

i have some images now for reference 

 the second is one i coloured, i could be wrong about the floor being stone. 

i’ve also quickly added some pillars to the room to show what that could look like. but take note that these are based off the archways, the pillars in he rest of the ruins look different.

For you undertale timeline 

This is only something little and is probably either an oversight or a stylistic choice but I haven’t seen anyone else mention it and I thought it was worth mentioning. 

When Chara falls there are pillars in the first room of the ruins, with vines growing on them. By the time Frisk falls they’re gone. I don't know how much time would have to pass for them to wither away but I assume it would be a long time.
