Core settings:
The world is eroded by a different-dimensional space called "Audio Track", and all selected people will be pulled into randomly generated "movement copies" with themes ranging from classical to electronic, from folk to rock. Each participant will be bound to an exclusive musical instrument when awakening. The musical instrument is both a weapon (can release sonic attacks and build sound wall defense) and a key to pass the level (you need to play specific fragments according to the dungeon melody to unlock the mechanism). If the copy fails, it will be swallowed up by "noise" and disappear completely; cumulative clearance can obtain "music theory value", improve the ability of the instrument or unlock new songs.
Intention: good-looking
