I've just taken 0.1.8 for a run.
Holy cow, the fire is impressive. Visually indeed, and also in gameplay. I usually have to fight Mrs. Slitherss long enough for the battle to build to epic levels; with the gas canister I just burned her out as she was finishing saying "there's more than one way..."
From the perspective of modesty and decency I should tell you to nerf the fire... however, I won't do it, at least not tonight. Its power is gratifying.
