I need graphics from Blood Stained Sanctuary, which is a level in Cave Story.
If they could also be recolored to SMB3, that would be awesome.
Here are some screens of this level to give you an idea of what I require (don't bother with the NPCs, UNLESS you are willing to try to make the Press [the grey, 1 and a half tile high, 1 tile wide things that act like thwomps]).

(I would've used screens from the original (as in, not Cave Story+) BSS, but I couldn't find any).
For the background, I'd recommend having it replace the green SMB3 "battle" background (but any background that can scroll a long ways horizontally and vertically without glitching will work too).
