Is it in the plan to eventually have the grapple effect come out of the arm? Right now it seems strange to have the arm out without it visually serving a function. Some motion to the arm while moving would help immersion a lot too. As is I’d rather see a nicely designed cross-hair to convey whatever information the light on the arm is and hide the arm.
That being said this game looks fun! Grappling hook style mechanics always makes everything better. Would definitely play.
