You are a spark on a tether, orbiting an anchor you have to defend, and you never let go — the only thing you control is how much line is paid out. Reel in and you spin up into a buzzsaw parked on the core; let out and you become a slow scythe sweeping the whole rim. The glowing ribbon you leave behind cuts too, so you are not aiming a dot, you are painting a blade. Wind in too long and the tether burns through, so the game is a breath: in to shred, out to cool.
