It just feels slow and I also think it would be good if it automatically reeled you in when you grapple. Also, at the very start I started to just go right for some reason. Not sure why. The hitboxes seem fine and art may help a little. Screen shake is great for adding some extra juice. (If there was screen shake sorry I didn't notice.) I'm glad you want feedback to get better! 

I could be wrong tho. 

(Good job taking criticism! I need to get better at that lol)
