A little demo I created to test out palette cycling effect.
and to try playing with a shadow effect which I'm pretty proud of.

So why not recreate the boing demo for the commodore amiga which also used palette cycling effect.

for the shadow I created my own line drawing function using Bresenham's line algorithm

I have taken the ball sprites from Two_Owls because my original ball didn't look too great.

drawing the lines with shadows could deffinetly be improved, especialy because we know the size and location of the shadow :P

Quite possibly the best Amiga Boing I've seen so far, @jeromkiller. And there are a lot of them for Pico-8. Gold star work.

Here it is a bit smoother - and I changed the audio. Best audio I could do with the limitations of Pico-8.

Compare with original, 30-seconds into the video.

I'm currently seeing if I can improve the background line drawing, by finding the intersection points of the background lines and the shadow and then using regular line() calls to speed up the drawing of the shadows.

I think i might have to go over my math again, because the lines break if they get too steep,
And the three line() calls don't produce the same line as a single long line, so when the shadow moves that might cause the lines to jitter around.

Edit: haha yes, everything jitters
and its only a little buggy XD
