Yeah I agree.
I'm not sure if increasing the range would have made an impact, but clearly indicating whether or not you are inside of the field as well as allowing the player to still be hooked/pulled split seconds (40 ms say) after they exit the field might have helped (since human reaction time is around that number + time for you to press the button). I thought of this during development, as well as the possibility of slowing down game time as you approach a gravity well, but I didn't put too much priority into implementing this. Thanks for letting me know it's an issue.
