How to Play Getsu Fuuma Den
Quick start
Select the starting method from the title and first proceed along the path of the field. You will move to the action side when you come into contact with torii gates, stairs, or enemies, so on the 2D side, check the enemy's distance and attack with B, and adjust the jump height by holding down A. Avoiding duplicate purchases at the store and refraining from giving advice will stabilize your search.

The 3D maze records the direction you turn and attack the doors to open your path.

Getsu Fuuma Den — About this game
"Gekufumaden" is a Japanese-style action RPG released by Konami in 1987 for the Family Computer. To exact revenge on the dragon bone demon who defeated his brothers, the main character, Tsukifuuma, walks across a large field, entering through torii gates and stairs into a side-scrolling battle plane and a 3D maze from a first-person perspective. The goal is to improve the power of your sword by defeating enemies, collect tools and information from shops and shrines, and collect Hadouken and Demon Masks hidden all over the place. Use movement, crouching, jumping, and melee attacks in the 2D plane, and explore the 3D maze without losing sight of branches and doors. Even after the game is over, you can use continue and resurrection spells, so you can record the information you have obtained and progress little by little.
