The purpose of the game is to only work once, sorry if that is an issue for you. It is possible to reset the game, but you are gonna have to delete a savefile (which I have no idea what it is, all I know is that it's really far into files somewhere)
Ah, I see. Is the file still in your recycle bin? If so, you can just recover it from there.
If not, I can just copy and paste the text here. Sorry for making this tedious, but I would rather leave that element as a surprise for other people if they decide to look at the comments before playing the game.
