1st rating of the overhaul, I think it's great, having it be rings feels weird still because it's like if the engineer from tf2 pays with his blood to make his machines, It's at Its best in boss fights, but I think a separate counter for metal would go a long way to great, and it doesn't have to go far.
(Never understood why the dispenser just gave back the rings that were used to make It, the dispenser is gone now, so this doesn't mean anything anymore, but it was still weird)
