Flickering ember effects for my game's opening crawl with some randomized sizes and movements

Started working on a little top down RPG game while I learn PICO-8 so I'm calling it Ragged Souls alpha. So far the title screen is the only thing close to finished but I'm liking it already.

(note the title screen 'music' is the sound of waves)

Ragged Souls is NOT a real game - at least won't be anytime soon. I've only begun learning how to make software but I wanted to try making a cool looking title screen in the 128x128 resolution so that I have a vague idea of the kind of end product I'm working toward. Title screens also seem like a fun way of practicing pixel art, so I might make more on the side.
