So glad this game randomly blew up and got super popular because it deserves it! This game is everything I've ever wanted out of a video game from the general aesthetic to a lab rat protagonist to being a rhythm game with Dyes Iwasaki's music. It definitely suffers from the typical NIS difficulty but I expected as much. Not a single bad song in the game either, some definitely more memorable than others but everything I've caught myself humming to myself at least once or twice.
