I might have missed something. All I did was buy the license upgrades, then fuse minerals up to lightning, throw them in the core, and repeat. Visited the oven once or twice and it just caused pandemonium. Eventually I bought all the upgrades, and then there were too many robots on screen so I gave up.
Real pleasant though! Breaking the rocks is satisfying, I could do that all day. (heh pretty much did do that all day)
