What is an efficient way of making a pixelart game without having to scale every sprite up

[twilit jewel]

I usually work on pixelart games but this time I need the sprite to rotate but the pixel should not get messed up. I don't want to scale every sprite by hand, this would take too long and mess things up. What is a good way of doing this?

Rotate in-engine instead of the art

use skeletal animations within the engine instead of doing it in the art program, use bones
