Thank you for trying out the game and for the feedback! I agree with your feedback. Although you can double the length of the grapple in the assist settings when you pause the game, I also thought that there should be an indicator of how long the grapple can travel from the player so that its not ambiguous how far it can reach. My plan was to have a toggleable and subtle ring-like indicator around the player indicating the grapple max distance. But alas, I ran out of time to implement it. Maybe for a future update!
Thanks for playing our game! Cheers!
