Mr Mucky Guitar Legend

You control a character, presumably Mr Mucky himself, who is playing a guitar on stage. The core of the game is watching colored notes, shaped like guitar picks, scroll down the screen toward a target line. You press the corresponding arrow key as each pick crosses that line. Some notes require you to hold the key down, with a blue bar showing how long to sustain it for a higher score. The main objective is to hit these notes accurately to complete the song and keep the crowd entertained. The pace picks up as the song continues, and missing too many notes can end your performance. It feels like a frantic, focused test of your coordination, trying to keep your fingers in sync with the music.
