This game confused me a bit. It wasn’t clear what a lot of the upgrades did, and safety was never an issue for me? The money/sec seemed to flash a number whenever I sold, but there was nothing passive at any point. I don’t think there was a goal, and the graphs and the number of neutrons never seemed relevant.
I’m guessing these were all things you were planning on implementing, hence the “ran out of time” message? That’s fair enough.
