Root Rexx
stylized as ROOT∞REXX, is an otome visual novel video game developed by Otomate, exclusively released for the PlayStation Vita by Idea Factory on January 22, 2015 in Japan. The game follows Mochizuki Kazune, a teenage girl who meets members of the fictional boy band Rexx. Gameplay
As a visual novel, players read text to advance the main story, occasionally making decisions on how to progress which ultimately effect the plot's outcome. Like other Otomate produced visual novels, players' story selections influence which of the six band members the main character will romance. The game also features an optional music rhythm game, with playable tracks being unlocked with different endings achieved during the main story. This side game plays in a manner similar to other touch screen based music video games. Music notes will gradually approach one of several circles located on the same side of the screen, with the player tapping the note once it overlaps with the locked circle. To successfully perform each action one must tap it as the falling timed circle converges on each main circle, or swipe in a direction indicated by an arrow over the note. The timing follows the rhythm of the music. By successfully hitting notes concurrently, a combo can be chained. Occasionally, players will need tap the Vita's back touchscreen. Because these music games are entirely played with the Vita's dual touch screens, this mode is not compatible with the PlayStation TV. By completing a music track, side stories can be unlocked, which function as visual novels akin to the main story. Release
