So my finger after one level is now almost numb. But that aside on to the review.
Ok so the game plays well, looks great, sounds are perfect but there are three bugs I found.
The first one being that the UFO ships once the game got to one or two humans they would bounce of the side of the wall. The second being the Mother Ship (red UFO) once the game got down to one human didn't fire or would fire but not hit the human. Last but not least the Aliens would stand still and not go after the human. All that being said it was still a great game but not for more then one level.
Overall I rate it 3.5 stars. Great job keep up the good work.
