I like the concept but I was confused during game play. I'm not sure how to place the defence to stop the bad guys. I placed one and it stopped a few of them but the other blocks didn't stop them. I also couldn't craft a canon (I think it was a canon, sorry if I misread even though I think I had enough parts). The intros really get you into the game and I really liked them. I also really like the different music and sounds based on locations!!
