I played it a bit a decade or so ago. I never really got the hang of the main, game-defining mechanic; one of the main methods of movement in the world was to jump from a high point and build momentum while gliding to get higher, but that was also the main way to deal damage, iirc. It was very strange.
As for the crassness, the original Worms game had a self-destruct attack that was about as direct, iirc.
