Each of the game 's eleven stages include five rounds of increasingly complex block patterns for <unk> to clear . The ten different block types vary in <unk> and points value . A well @-@ timed hit of the <unk> gives <unk> a powerful bounce to break through harder blocks . Another block type turns the remaining blocks into a bonus round that rewards the player for clearing the screen in the least amount of time . The player can find <unk> stars that lead to minigames , such as air hockey , where the player can earn extra lives . The rounds also include enemies to attack and avoid . Some enemies contain bonus items . Each stage ends in a boss fight .
