Was good in the beginning but becomes tedious requiring lots of energy to accomplish nothing. Update:03/31. In response to the developers comment. I believe the rating is fair. I truly was hooked on the game I thought it had an interesting story line. Then it was over and you spent about 5 minutes at a time clearing blocks out of your way exhausting your energy. Of course you can always BUY the energy which it was clear was the point but it wasn't that great.
