Loved the fire! Took me a while but I beat it! It has a very slow start but gets really fun towards the end.
I didn't fully understand how turbo worked until way late into the game, it gets really intense!
I liked how it takes a while for it to become "self sustained" in that you don't need to input anything to still grow.
My only real complaint is that I would increase the rate at which the stokers collect scrap, it felt like the stokers barely collected any scrap at first, it took turbo to reach 1000% for it to be noticeable.
