I found a way to keep arrows on auto-attack. Hold "A" button to keep firing arrows, then click in a new tab on the same Internet Window and let go, the arrows should keep firing so you don't have to hold "A" for the entire game.
for real...and I feel thr games growing on me a little, kinda like it now. Watch in a week or so ya wont be able to tear me away from the game like most flash games I try.
