Very nice. I like the bomb exploding the terrain and then splitting into several bombs. This reminds me of a game i use to have as a demo called Castles. In that you had your own castle and had to shoot weapons to the other castles and destroy them. The castles image acted much like terrain when it got hit and reflected its health. And there were many sorts of weapons and upgrades for your castle.

thanks :D that bomb is inspired by cluster bomb in Worms. More weapons later.
