Possible to rotate particles so that they point in the direction they are bursting?

[jln19]

The fireworks animation is great, but I'm trying to have a custom particle burst away from the center in a flower shape. You'll notice in the screenshot here that all the particles are vertical - I want to rotate them so that the larger end is pointing away from the center of the burst. I've looked through and played with all of the parameters and can't seem to find the right one to adjust.

let explosion = VortexSystem(
				tags: ["circle"],
				spawnOccasion: .onDeath,
				position: [0.5, 0.5],
				shape: .point,
				birthRate: 1000,
				emissionLimit: 100,
				speed: 0.5,
				speedVariation: 1,
				angleRange: .degrees(360),
				acceleration: [0, 0],
				dampingFactor: 4,
				colors: .randomRamp(
					[.white, .pink, .pink],
					[.white, .blue, .blue],
					[.white, .green, .green],
					[.white, .orange, .orange],
					[.white, .cyan, .cyan]
				),
				size: 0.15,
				sizeVariation: 0.1,
				sizeMultiplierAtDeath: 0
			)
