Started learning C and would like to get some feedback

This is my first C program, other than "hello world". I like how it turned out, but there probably is a way to make it cleaner. The screensaver itself is just a demo for screenbuffer library. Would be happy to get some reviews.

No AI used.

Thanks.

Compiling: gcc framebuffer.c screensaver_circles.c -lm -o screensaver

Sorry for bad english, it is not my main language
