Yeah, snapping the line sounds like a good idea. Maybe give the player visual feedback for when it's about to snap, so that it doesn't feel unfair. Maybe one of the upgrades could be to make the line longer?

That's a great thought as well! Riffing off your idea, we could have some visual animation of a rope getting taught and vibrating right before snapping with sound cues to warn the player. A longer rope would also be a great upgrade if the rope snapped. We also thought it'd be cool if you could pull things towards you with it, such as the large derelict ships.
