Very neat mechanic! Slinging the ball alongside the trail effect feels satisfying.
I do like that the camera pans towards where you're aiming, do think it could help to zoom it out a bit more/make it pan a bit more! I had a few times where I was aiming blindly, not sure where I would end up.
Regardless, cool mechanic! Since it's called Colorsling, I wonder if changing colors could add onto the mechanic?
