Orange Pocket: Cornet

The gameplay requires little interaction from the player as most of the duration of the game is spent on simply reading the text that will appear on the screen; this text represents either dialogue between the various characters, or the inner thoughts of the protagonist. Every so often, the player will come to a "decision point" where he or she is given the chance to choose from options that are displayed on the screen, typically two to three at a time. During these times, gameplay pauses until a choice is made that furthers the plot in a specific direction, depending on which choice the player makes.

There are ten main plot lines that the player will have the chance to experience, one for each of the heroines in the story. Eight heroines are from the original game, and the last two come from the console versions, though both versions only get one of those two heroines; therefore, there are nine heroines in the Dreamcast and PlayStation 2 versions. In order to view the plot lines to their entirety, the player will have to replay the game multiple times and choose different choices during the decision points in order to further the plot in an alternate direction.

Orange Pocket's story takes place in a rural area in Japan near a large mountain and river. The protagonist, Hideaki Eda, is attending East Tsukuda Academy (東津久田学園, Higashi Tsukuda Gakuen) and is experiencing an enjoyable life. One day, Hideaki's childhood friend Nazuna Ayase returns from the city and starts attending his school. She adapts to a rural life quickly and soon things start to become noisier as Hideaki begins to hang out with more girls from his school.
