I'm planning on having day/night cycles in my game. At first, I thought there'd be one "day" version and one "night" version of each background, but I got carried away playing with all the colourful little pixels and here are a bunch of attempts at creating different lighting conditions using EGA.
If this was boring ol' 256 colour VGA or whatever else the kids are using nowadays, all I'd do to make a scene lighter or darker would be to slap a transparent layer of that colour on top and call it a day. YAWN. Or maybe edit the actual light source if this was one of those terrifying 3D games.
I'm much happier picking away with my digital cross-stitching :P.
Here's my other game art.
