i like but yeah as said previously its kind of spammy.
what i have done on an archery challenge of mine is to make it so that on certain targets when your arrow hits it, either the arrow fires back or on a harder difficulty your arrow fires back at you and 4 more arrows fire from the target rather fast, so not only do you hit the target you get shot at and have to dodge.
i also put a small dummy made out of bricks behind the firing line of the hard target and when an arrow hits it blood pours out. (not really a blood emmiter, just plates that change colour)
i just thought you might like to put that into your post.
