It took me a while to understand what the hell was going on, but it became strangely addictive after a while. I think if you added some explanations on what different things do so that it's not so opaque for first timers, it would help immensely. I also thing this has the potential to be a great time-waster like clicker games. It just needs some more variety in mini games.
The only real complaint I have is that the performance goes from fine to chugs-ville after a certain point. Especially on the Dig Up stage.
