Nice, loved the setting! I couldn't memorize all the keys on the first attempt, but played through on medium then. Not quite sure if I missed anything, but there didn't seem to much of a challenge later on? I shoved coal from the tray as fast as I could, upgraded until it wouldn't want to anymore, and then it was just pressing the "reroute" button once in a while.
I like the visuals, but they are so dark, it took me a while to see the automated coal supply.

Thanks! Yeah it's automation, so its meant to be easier at the end. The function I'm using to calculate power draw scales up very fast at the end, but the final upgrade is also very powerful. Maybe I will tune down the final upgrade a touch but I'm not sure how that will affect the hard difficulty, which I still want to be doable. Also, as for things being too dark, there is a brightness option in the settings you can change!
