I was going into this thinking the whole game would be the boss battles (no fodder enemies). You never know.
Another way for spinners to work could be like in touhou, where a timer appears and you have to do enough damage in the time limit for the bonus (or to clear the spinner). This way, the fast spinners can be done just by catching a few bullets on the enemy.
