the main gripes with it are
1) Too strong
2) Too similar to Hook
and while the former is definitely correctable, I can't imagine a harpoon weapon that doesn't feel like hook tbh

honestly, the next goal is to probably ditch the "return to sender" feature and the "stick to ground" and just make it a projectile that upon hitting grants 5 seconds of 'hook' effect(edited)
after your harpoon has been shot and it. is stuck somewhere, you could maybe hold your left mouse button to crank the rope slowly up and the movement down key to release the harpoon. Might be slightly complicated.
