Gyruss/YMMV


 * Awesome Music: It's J S Bach (and a barock version as well), what do you expect?
 * Polished Port: The NES version. Literally revamped the game to have history, power ups, sub bosses, bosses and more phases. Literally improved the games.
 * That One Boss: The notorious Boss of Jupiter in the NES/FDS version.
