So, I don't know what I'm doing really. I just click randomly and occasional some tiles vanish and children cheer. I don't know why any of these things are happening, but I like it.
I have to agree with inky. I see that one of my bridges doesn't work but first consistently does. No problem, change the second one and the workers break the first bridge that I didn't touch at all.
Fun except for some problems like this.
