In an interview with the game's producer Michi Ryu published on Siliconera on July 25, 2023, he revealed that the COVID-19 pandemic had a significant impact on the game’s development, which started just before the pandemic. The team had to adjust to an unfamiliar work style and structure, which made it difficult to exchange information with team members. Chat tools and video calls became crucial for communication during this period, which they normally did not use before.

Ryu mentioned another significant challenge during development was the unification of daimyo and retainers. The team wanted to show the theme of "living officers who think and act on their own", but found it difficult to decide to what extent retainers should act on their own. Some would act too smart and expand their territory if the player left them alone which Ryu believed would make for boring gameplay, but he also did not want to put extra stress on the player by making the officers stupid. Their solution to this was "not to indicate what is right to do but to let the players decide."

Conversely, Ryu could not recall anything that came together easily during the development process.
