Only started just today, but it seems interesting. I'm all about earning methods being more interactive. I like that there are many different things to upgrade rather than just one "upgrade production" button, it gives a greater sense of immersion. We'll see how this goes but I'm liking it so far.

Edit: I'm already stuck. I'm watching the video and entering the captcha but it tells me the captcha's wrong every time. I've done it maybe ten times now.
