I just finished the last campaign level (as testing of the new release).
I was so glad I can play the game for some time finally

Maybe you would like to see how my factory looked like

I finished the level in 1:09:00 and I believe it is possible to do it much faster.
I used several ideas of you (players of factorio) while playing the level, mainly the compact smelting line with the help of underground belt and balancer of the iron on belt.
I also took advantage of the new splitter piece, it is really useful when I had 8 towers and wanted to split the ammo production between them.
Here is the image of the factory right before finishing the level.
