The use of the theme is very simple you could have the camera bomb change to it after another camera angle like from a plane. You could also loose point or/and restart when you fit the ground.

The game could maybe have an ending when you destroy all the tanks, and if you hit the floor you could maybe lose some points or something, rather than clipping through.

I think the concept of playing as a bomb is interesting but the game does not end after you have destroyed all 3 tanks. The bomb itself also falls too slow.

nice use of a different prospective as you play as the bomb would be more realistic if the bomb moved faster felt so slow
