Great game, as always. But like always, there were some bugs that made me lose the game even tho I figured out the correct solution: Once I either accidentally or just for the sake of trying out different solutions picked one answer, it did not let me change it in some cases. I mean, I do hope it is a bug! Has happened to me in other ZS games, too.
But I do love these games. Keep making more, and hopefully we'll see a longer game soon!
