So I finished the game two times now and in the process I upgraded both the health and devil trigger to the max. Now I started to spend the orbs on the other items, like healh stars or gold orbs. I noticed the price of each item goes up every time I buy one, at first I assumed the game makes it more expensive the more of that item you have in inventory, making it pricier to carry too many at one time. But now I used some up and the price stays. Is the price just gonna go up all the time? That would suck, because in that case it would be wise not to use anything until the super hard difficulties. Or is there a price cieling or something?
