After playing for a while, I was mostly left with a question; "Is this clicking all there is?". It kind of felt there should be something more, something I just did not understand. Clicking fast enough becomes hard very quickly and it is difficult to get too far in this game before losing.
As a side note, the music in the main menu just sounded good from my headphones. I would have liked to hear more of that.
So, no secret for me this time.
