Similar to Parappa the Rapper, 'free-styling' in between obstacles gives extra points. Completing a successful streak of obstacles will help Vibri recover back to her higher forms, and clearing enough obstacles in succession while in rabbit form will evolve Vibri into Queen Vibri, increasing the player's score until Vibri is hit. Getting hit too many times while in worm form will end the game. Getting hit by obstacles too many times will degenerate Vibri from a rabbit into a frog, followed by a worm. Not pushing the correct button(s) at the right time turns Vibri into a scribbled version of herself temporarily. Sometimes two obstacles will be merged, requiring the player to press two buttons at the same time (for example, a block and pit combination will require players to press L and Down together). There are four basic obstacles block, loop, wave, and pit, which require players to press the L, R, X, or Down buttons respectively at the right time to navigate.
Vib-Ribbon is a rhythm game in which players guide the main character, Vibri, across a linefilled with obstacles tied in correspondence to the beat of the song. The game's main gimmick was that any CD could be inserted and the game would create a stage off of it, essentially allowing for endless levels. Vib-Ribbon (ビブリボン Bibu Ribon) is a PlayStation rhythm game developed by NanaOn-Sha and published by Sony Computer Entertainment.
