I presume this is a test game ? if so, concept is not bad, being able to draw your own defense line has some potential, its sluggisch though, I had to try 4 times before I was able to even make it to the other red dot.
Not bad, mine collision detection is sometimes hard to predict, helicopters sometimes hide behind the user interface. Oh, and easy down on the advertising... 3/5
Idea is ok, but otherwize its just very bad, it lacks speed, collisions are odd and controling the fall.. im not even getting into that 2/5 and thats just because I like the idea
