This was really cool! I'm big on minimalist, functional UI, especially for incrementals, and yours was spot-on. The game felt very balanced and having to maintain your pressure in the early game kept me feeling engaged as I looked through the upgrades and tried to make the various products. I feel like you wanted people to experiment with different temp/pressure/fill values in order to generate the products you need to progress, but I would have liked just a touch of guidance for the non-petrochemical engineers like myself!
