This was my first attempt at making a bouncing ball animtaion using the pixel art software Aseprite. I think this turned out pretty well; the motion of the ball looks quite smooth and has a nice speed to it.
There are 9 frames for this animation and I set each ones duration to 75 milliseconds as the default 100 gave it a bit of a floaty look.
This was the sweet spot as going lower made some frames harder to see; so 75 gave it a nice snappyness to it but still giving you time to see the frames in motion.
