Gee, I wonder if the Sea of Science and the Sea of Holes don't exactly make for inspiring level design aesthetics on the NES? And for completely opposite reasons, weirdly enough
The Sea of Science is way too many colors and geometric shapes distorting and stuff for a NES to ever handle. And the sea of holes is literally just that. Levels that are only two colors (and mostly white at that) I think were also hard to pull off on the NES simply because it limits the palette too much, I would think.
Still, what is done is highly impressive. I'm hearing Eleanor Rigby in my head even. Nicely done.
