Any extensions/way to combine files together

Hello, I’m wondering if there’s a way to combine sprites together, as I’m messing around with trying spiriting in a Rain world Style, which from my knowledge involves slapping multiple sprites of a creature’s body parts together, so i want to know if there’s a better way to combine sprites other than copy and pasting them all into one file.

oh and for the record I’m starting on dabbling on a rain world inspired game where you’re basically a monkey rat.

I rage quit that game bruh :pensive: :sob:
but it was pretty good
