Great. 100 recommend, think I'll go check out your other games after my exams!
I did find science kinda OP :D. My goto strat in hardcore was to focus solely on science at the start, getting things that reduce its cooldown in combination with several of the carbon-capture cards. Once you get the sci cooldown low enough it becomes quite possible to mitigate most of the +20 emission from 20th century industry. Amusingly, the key is also not to build any energy generating cards in the beginning (since they will decrease cooldown of the red sector and lead to more frequent emissions).
