What the developers have to say:

Why Early Access?

“We want to utilize user feedback to improve the content of this game.
By listening to the opinions of our players and fostering an active discussion, we can raise the quality of the game.”

Approximately how long will this game be in Early Access?

“Early Access on Steam will begin in May and anticipate it to last for up to a year. We can’t say exactly until when it will end as we want to work closely with our community to help bring this game to life through content review, bug fixes, and balancing. Keeping user feedback in mind, we will also consider extending the Early Access period.”

How is the full version planned to differ from the Early Access version?

“For the full launch version, we will add several stages, weapons and playable characters. Also, there will be adjustments made to the game balance as well as other optimizations patches. Users who participate in the Early Access will get a digital art book, original mini soundtrack and Famicom version of “GetsuFumaDen” as bonuses. These won’t be included in the standard edition, but are planned to be included in the digital deluxe edition of the game after launch.”

What is the current state of the Early Access version?

“While this is an Early Access version of the game, it still has a lot to offer.
・Highly strategic action that focuses on the pacing and timing aspects unique to Japanese martial arts.
・Beautiful and harrowing stages done in a unique Japanese art style.
・Fearsome bosses that are sure to leave an impression waiting for you on each stage.
・A variety of main and sub weapons which can be combined to construct diverse builds.
・Playable in 11 different languages.”

Will the game be priced differently during and after Early Access?

“The standard price won’t change, but users can get the following content if they purchase during Early Access:
・Digital art book *Japanese/English, approximately 30 pages
・Original mini soundtrack *15 tracks
・Famicom version of “GetsuFumaDen” *Available only in Japanese
We also plan to include this content in the digital deluxe edition after launch along with a standard version.
During Early Access, users can purchase the digital deluxe edition at the same price as the standard edition.”

How are you planning on involving the Community in your development process?

“We will listen to user feedback through the Steam community and apply it to the game. You can check what is being implemented by looking at the roadmap on the official website. We will look out for discussions not only on Steam but also Twitter, Discord, YouTube and Twitch.”
