In the final video of the first ever SpaceChem Tournament, GuavaMoment talks about how some puzzles require a lot of planning to work out how to solve them, "even before you place a single symbol down, just figuring out how to beat [them] is quite a challenge".

This is one of _those_. Most of my planning time was in Tabletop Simulator, shuffling coloured tokens around trying to work out how to add metals together in a way that could make sense to me.

In an effort to not make this a 7 hour stream, I'll skip most of my thinking process, and just say that I'm pretty sure that this is the hardest puzzle I've *ever* attempted to solve in any Zach-like game. And I probably didn't make it easier for myself by trying to solve the whole thing trackless and wasteless. But I knew that I would not feel up to trying to improve on this once I found something that worked.

And now that my brain has stopped melting, I can look forward to seeing much more optimized solutions than mine.

I might try doing more of these. Hopefully easier ones, though...
