The Japanese version provides infinite continues while they are limited in the international versions. (The exact number of continues depends on the difficulty setting)
日版无限续命，而美版欧版（统称国际版）为有限次数，并且次数取决于设置难度。
The Japanese version allows the player to fight the true final boss on Normal mode, whereas the international versions only allows it on Hard mode.
日版允许玩家在正常难度下与真最终boss对怂，而国际版只允许困难难度才可以。
During gameplay in the Japanese version, the lives counter counts "1" as your last life. In the western versions, "0" is your last life.
