Perhaps use souls to purchase upgrades between stages, or between runs. Maybe use to purchase new guns? Also, maybe start with three health instead of one. Another thing I noted is that bullets and bloater gas still appear outside of the light area, which can be used to tell where zombies and where they die. Though this may likely be intentional.
Hey, I just want to say that I love this game, and I'm so happy that a mobile version will be coming out. I have a suggestion, though it may be difficult to implant. Make it so where your game can also save to your Kongregate account, and then have it where you can log into your Kongregate account from the mobile game. Also, I think it would be interesting to add a gilded Cid, though I can understand why that would be dificult. All in all, a great game. I'd even go so far as to claim it as my favorite idle game, and one of my top ten favorite games in all.
