Getsu Fūma Den

In the first years of the Demon Age, a horrible demon named “Dragon Master”
was revived by his minions in hell. To protect the peace of the overworld, the
two eldest Fuuma brothers fought the Dragon Master. Both were unable to defeat
him and were killed, losing their legendary Wave Swords, also called
Hadoukens. To avenge their deaths, the last of the Fuuma brothers vowed to
slay the Dragon Master, and take back the Hadoukens.

_Getsuf ūma Den_ is an action game with slight RPG elements. You travel
through the overworld on pre-determined paths, which branch most of the time,
leading you to shops, places where you can encounter other characters, and
dungeons. Once you descend into a dungeon, you navigate your character on a
platform, jumping and fighting enemies with your sword or other weapons. There
are also a few first-person dungeons later in the game. In the dungeons you
can collect money and then use it to buy weapons and other accessories on the
overworld.
