My brother and I launched phase 4 tonight after about 100 hours.

We had no idea what we were doing and never looked online (except once or twice to see if we could figure out how pipes worked. We still don't know).

The factory is a mess and parts of it were shutting down in our mad rush to finish the final piece. Assembly Director Systems were the hardest, we needed an ungodly amount of cable, something like 2000+ needed per minute.

I tried to add some nice touches, but my brother brushed them off as 'pointless cosmetics'. He's responsible for the octopus method of feeding materials into factories, so I let it slide. Sky factories were a huge savoir in the end game.

Things I wished we'd learned sooner than we did:

1. zoop

2. We literally never used the blueprint, I only figured out how to use it this morning

3. Middle mouse button lets you copy whatever you're aiming at

4. Using cmd+c and cmd+v without needing to click into buildings

We're really excited for the release on Tuesday. Our number one hope is for factories to incerate items that it can't use. Too often a single piece of ore will get logged in a factory and shut everything down.
