lots of fun blowing things up
graphics are adequate. sound also. background music is derivative, but catchy. little bit of loading between levels.
i never got to play mulitplayer (none of my friends have a ds, and i'd rather be online listening to music than playing a game), so i can't rate that part, although x-play states that it is the most interesting part of the game.
timing is key: the explosions of the different kinds of bombs versus the speed of the different monsters. i finished the main game levels and put it down. finito.
