Nothing really, just flip the "slow" slider to slow down the droplets and understand what's happening.
Everything by me HOW IT WORKS: The blue droplet, (named "Boop Boi") is constantly chasing the teal one, (named "Shy Boi"). Shy Boi teleports around randomly. Shy Boi will draw a rainbow trail wherever they go, so you can see art. TL;DR: teal boi run away from blue boi while making rainbows.
