its simple, dodge the bullets for as long as you can, the number at the end is the time(in seconds) you survived orange bullets won't hurt you if you move though them blue ones won't hurt you if you stay still when you're yellow, then when you press space it will spawn a yellow bullet that will teleport other bullets to a random location all other soul colors are quite easy to understand bullets can cover spawn area and damage you when you spawn but I'm to lazy to fix it
Soul from Undertale, by Toby Fox most of the soul colors are also inspired by Toby Fox's Undertale. Everything else I made myself
