The game's director Hato Moa handled most of the writing and programming, with fellow doujin artist Damurushi assisting with some minor aspects of the writing and art direction. Most of the game's development was spent gradually writing the narrative, which Moa described as mostly being "randomly thought up" as she went along. The exception was the mystery in the game's true ending, which she felt was the most difficult part of the game to write and impelled her to consult with an unspecified "pro" to work together to finish it.
