Sora o Tobu, Mittsu no Hōhō.

The gameplay in Soramitsu requires little interaction from the player, as most of the duration of the game is only spent on reading the text that appears on the screen, representing either dialogue between characters, or the inner thoughts of the protagonist. Occasionally, the player will come to a point where he or she is given the chance to choose from a list of options that are displayed on the screen, typically two to three at a time. During these times, the gameplay pauses until the player makes a decision, which effectively furthers the plot. There are multiple plot lines that the player may experience. To view all of the plot lines, the player must replay the game multiple times and make different choices to progress the plot in an alternate direction. One of the goals of the gameplay is for the player to view the hentai scenes depicting the protagonist and the heroines having sexual intercourse, in addition to the game's story.

Soramitsu was first announced to the public at Broccoli's 2007 content lineup media conference as the second project of the visual novel studio La'cryma,[2] a collaboration among visual novel studios Broccoli and Circus. Unlike its predecessor True Tears, neither visual novel studio GameCrab nor Japanese illustrator Rei Izumi were involved with the project. Instead, the position of scenario writer was given to Yū Kamiya, who has also planned the project, while the position of art director and character designer was given to Hirō Ōgi,[3] with additional art design by Masato Mizuki, Haruki Kazami, and Yuki Takano.[4]
