I hope the scaling of the heat vent comes soon, im not sure, but i feel like since the max of the heat vent is like 2.5M, the percentage of heat coming from the exchanger is based on that... so the heat vent doesnt get full capacity of what it can clear,,,
Breaking down your reactor into 3 parts: "Heat build-up"(uranium, stufff), "storage"(large capacity containers) and "disposal"(heat vents). Make sure the storage and disposal unit is connected with large quantity pipes, this way, its much easier to manage, make sure to not do anything crazy... tubes dont transfer heat that fast... late-game you will need more then 3 tubes per heat vents....
needs an epic final sequel, to make it super challenging, there should be like 4 different colors and 2 shapes! can't wait to play the ending of this heart-moving story of love, joy and clicking!
