Love these kind of simulations, I had really fun trying to hit the energy estimates. Reminds me of a mech simulation game we did for another jam.
Sometimes the game stopped responding for a few seconds when I switched views, but for the most part it worked smoothly. I wish I could switch view with WASD or the arrow keys.
I really like the graphics, simple but effective. Really sells the illusion that you're working in an old nuclear power plant. The text was a bit blurry in a few places, but that's really nitpicking :)
The minimalistic audio worked well too. Great background music to set the mood. All you really heard after a while was the geiger meter, of course :D
Great job! Hope you had fun making it!
