I finished all the levels. It was fun. It wasn’t 110% clear if I could do better cause the rules are intuitive but not completely clear. For instance, I didn’t know if an extra heat pipe is always worth it and if I could/should go for cheaper insulation or not? Experimenting didn’t feel meaningful. I wanted to know why things worked or failed. What exactly were the underlying rules?
I still beat the game and enjoyed the levels and game mechanic.
