 Battles in The Thousand @-@ Year Door borrow elements from the original Paper Mario and Super Mario RPG . The turn @-@ based system , in which players select an attack , defense , or item from a menu , is augmented by timed button presses that can result in substantial attack or defence bonuses when performed correctly . A similar " action command " was also used in all released Mario RPG games . In The Thousand @-@ Year Door , each of Mario 's party members now have their own heart points ( HP ) and may receive any attack that Mario can receive . When a partner 's heart points are reduced to 0 , the partner becomes inactive for the rest of that battle and later battles until recovery . If Mario 's Heart Points are reduced to 0 , however , the game ends . Flower Points — which are required for special moves — are shared among Mario and his party members . Defeating enemies awards various numbers of Star Points to Mario ; for every 100 Star Points , Mario is able to level up . Mario can choose to upgrade his heart points ( HP ) , flower points ( FP ) , or his badge points ( BP ) . The battles take place on a stage in front of an audience ; if the player performs well in a battle , the audience can assist Mario by replenishing star power , throwing helpful items on @-@ stage , or inflicting damage on the opponent . Conversely , the audience may throw damage @-@ causing items at the player or leave if the player performs poorly in a battle . For every 10 levels , the stage will increase by fifty audience members for a total of 200 after level 30 .
