Result of a fever dream where I wondered what if the NES had a kind of "special color mode" where it could output more colors per tile (8 instead of 4, for instance), with the tradeoff being using less colors in other tiles (less than 4).
Hence the liberal use of dark spaces.
I'll readilly admit I didn't think it through 100% so I'm sure there are inconsistencies here and there ^^;
And I also took some (but not many) liberties with room layouts.
Nonetheless, these can just be considered as a mockup for a more colorful NES Castlevania. Hopefully, I did a good job retaining the raw feel of the original.
Also, all of these are using the "standard" NTSC NES palette found on Wikipedia. Eventually, I'll test other palettes available.
