You maybe should add the possibility to launch a saved game from the beginning. I mean I played a while and exported the game using option in the Setting menu. And now to import it.....I have to play a while until the Setting menu appear ? :-)
I think you had a good idea making this game. An idle game that can learn me something. BUT I also think it lacks a save option (my PC is not powered on 24/7, yeah I know.... ^_^ )
