It's okay. It doesn't explain itself a lot, like why does my score up without me doing anythzing missing every equasion and molecule? I don't know. It's more of a mechanic display in a wrapper of sciene than much of a game. But it's okay, fun for a minute.
But topic missed: There is no man vs. nature in this, could be debatable since science explains laws of nature it might be somehow the themen but so subtle I count this as "Topic missed".
