Actually Kid Chaos has about 160 colors for backgrounds, etc. and not just copper gradients. Pretty clever use of a 2bit playfield (yes 2, not a typo . There's a few interviews with the author around the net where its spoken about.
Hmmm, I'd have to say that it does look like 3bit graphics, though it is impressive to get that amount of blitting... Perhaps only possible with a 2bit playfield...
As for the fixation with rave/techno type music, Id hazzard a guess it stems from the fact that its easy to write and requires no real talent. It can also be written with small samples so has a small memory footprint.
(sorry, being that Ive been an actual musician for over 20 years I have a particular dislike of that sort of garbage
That's a bit harsh, There are three types of music:
1. Music as art, the exquisite works of genius.
2. Music as entertainment, the crap my girl friend listens to...
Both are valid and often crossover!
Oh, then there's the third type... Utter ****e that has no purpose or value... I believe this is often referred to as black eyed peas... But I doubt anyone actually listens to that.
