Awesome! Next time I see a guy on a street corner preaching doom and hellfire, I'm going to give him a hug... In hopes of preventing this kind of disaster in our world. Imagine those giant purple bile-and-bone-spewing worm-beasts attacking busses and crawling through subway tunnels... What a mess that would be. Not to mention that only the most evil of people are safe from it, relatively anyway. This is a nasty thing to spring on a game world. I approve.
I like it. Racing across gears has always been a favorite mental image of mine. I typically imagine a clock-tower-like setting, but this oven is a great place for it, too. Race up the gears and watch out for your back end, there's fire on the way. Very cool.
