I played this more then I think I should have... LOL
It's really fun and challenging, I watched your walk-through and learned how good the bow upgrade is at taking out rows of enemies so I gave that a good 5-8 tries... I lost track... Well I gave it one good last try... for now... I may come back. But after kiting the boss around for like 15 minutes I was taken out by a green guys arrow... :(
