On Level 2, I was having a lot of trouble with this. I realized that I just needed to aim the drill so that it went directly into the building from the top and not the side. This was a simply flawless game and I am so glad Nitrome keeps pumping out this fantastic stuff! Who else could turn blowing things up into such a sport? Well, you weren't supposed to blow everything up as you had to protect some things. It was funny even when the buildings were destroyed.
The sounds and everything else was extremely authentic as well. I loved the relentless sounds of dust and rubble being blown everywhere. The graphics are fantastic and they are well organized. Everything is just so amazingly colorful in this too. I even love how these little people just move around the ground. I hoipe you continue to make these awesome games that are so well detailed.
