Once you upgrade your reactor core (and reactor shield), the temp goes too high, and I haven't found a way to set the rods higher without overheating. Therefore, those last core upgrades feel kinda useless.
That said, I loved the aesthetics and gameplay of it! It really feels nice to manage the reactor.
Ah, and about the contracts: Are they already fully implemented? The graph say maybe "200KW to 300KW" while my turbines generate circa 12MW each, so it seems kinda wrong... I mean, even a single turbine would generate a lot more than it's needed.
I'll keep an eye out for updates ;)
