The main gimmick in this game involves hypers - hold down bomb when your gauge is max to unleash them. You gain twice as many bomb and life fragments this way and you can obliterate bosses entirely.
As for the plot, that is for you to find out on your own.
--This game is murderous on your processor. You may want to go into config and toggle the effect cuts. The higher the number, the less effects. Note that the game is not fully optimized.
