How do you start a new game? I chose the first two "no" options and now I'm at a end.
I'll need to add a restart feature, sorry. That slipped through the cracks.
In the meantime, you should be able to use the info button on the left to go back to where you last picked no and select the other option.
Alternatively, clearing your browser cache should also reset the game, but the undo button is way easier.
