Making renders look like pixelart?

I know that with Freestyle, I can make my renders look like a 2d cartoon, but is there a way to make it look like pixelart? I need to make several animated assets for my game, but these would be tricky to animate by hand in a pixelart software as they contains some 3d elements to them (such as platforms rotating on a perceived depth axis). I’ve tried to render them normally then use color reduction in a graphic editor but results weren’t good. Also, related - is there a way to render animation as a spritesheet?

I don’t know about rendering as a spritesheet but might this tutorial be what you are looking for?
