We could set a limit on the number of colors and let the programmer decide which ones. Maybe 320x200x16 colors. So you can use C64 colors, ZX spectrum, EGA, or your own palette.
16 simultaneously shown colorsor 16 colors at all?
Closing date people??
I think most are all happy with a retro 320x200 virtual resolution and a 16 colour palette of your choice as a game theme. I love the idea and think it's gonna be a lot of fun especially on the creativity side of things.
January 6th would suit me better, Christmas is a very busy time of the year! I'm game for the 6th then!
