pretty good
It would be cooler with better physics. First of all, you need to count the momentum of the plain in determining the way the bomb falls. Bombs don't just fall straight out of the sky, they fall out of the plain at a curve. Since your plane goes at the same speed the whole time, it shouldn't be too hard to make the bomb follow this. Also, the plain is PAINFULLY slow. I like the music, and other than that it's a cool game.
