Very solid demo, kind of a production chain loop where you can reorganize/respec at will based on what you're going for. Pacing feels good until the very end, which is just letting automation run for a few hours, but that's obviously because that's where the demo ends. I liked how the story is doled out in literal sentence fragments as you unlocks upgrades as well. It's even non-linear based on what upgrades you prioritize.

I did have one odd glitch where tabbing out and coming back to the game would sometimes give give me anywhere from 2 to 20 minutes of idle time production, even if I was only tabbed out for less than 30 seconds. I couldn't reliably replicate it, but it happened a lot.
