Please add something that tells me how much money per second I'm making off the current item, to help us figure out what we should be crafting in order to make the most money.
Anyone else thing the guy with the cannon needs some kind of buff, as it is you could almost skip him because his damage-to-gold ratio is so bad. I think he needs to either have his attack be AoE, it would fit with the cannon, and give him value more in line with the others.
