Almost a good game. Upgrading by collecting coins while the fire rages out of control is not a very good system though. I'd say a point system with certain point amounts rewarding a certain number coins would be good. The better you do at a level, the more coins you get. That would make the levels replayable to try to get do better to get that 5th coin or whatever.
Needs perk reset and confirmation when selecting perk. Early levels of guns (aside from the pistol) are too weak and too much of a pita to level up. Fun game, though.
for some reason a bunch of my achievements aren't there. You need to add a retroactive check. If I'm guild master of the enforcers, I have to have been every rank below that.
I stand corrected about the weapons. The single shot weapon upgrades to be very powerful (overpowered pretty much). It's the only weapon choice, really.
