Lots of fun!
I have always been a fan of games like these and this is no exception. The thing that really works for this is how it wasn't too elaborate and just had everything it needed in order to be good. The music was nice and suited the game well. Another cool thing was how you never knew how some stray bits were going to fly off and kill an enemy. I think this may be the first game like this that I have played where you had to stop someone from being killed. It kind of makes you wonder why the guy is out there in the first place.
This is still tons of fun as even the people make funny noises as they die. It can be hard to aim something. I think you have to specifically point your mouse to a part of the construction as hitting them directly would be too easy anyway. You do not know how there are going to be tears in the construction too. The levels are all around quite unique.
