Only a few of these are known characters, Dr D. Most are just spur of the moment doodles, and a couple are ones only me and maybe a few others would recognize. The known characters so far are Mario, Luigi, Sonic, Link, Hitler, Santa, Megaman, Slime (DQ), Lion-O. A lot are inspired from other characters, like the Gnome, Cyclops (I dig The Odyssey), animals, some are stereotypes, ethnicities and professions. Really if I had too, I don't know if I could think of 64 known characters.
Yeah, I haven't messed with the palettes since the second update, they're pretty much set in stone, now. As for the mess of colors, some of them do look pretty jumbled at 1x zoom, but I really wouldn't recommend viewing these on anything less than 2x zoom at 1024x768. I'm not sure if this forum has issues viewing zoomed pixels without blur (I never get blurred pixels anyways), so if it does, you can zoom cleanly
here.
As for spacing them out, I think I'll do just that, once I get them all done, make a window/border to place them in, and spread them around on a larger canvas. I'm making these in
YY-CHR through wine, and for whatever reason, the copy+paste feature is broken, so spreading them out will have to wait until they're all completed.
