Some FNF arrowchart type thing. press space to start it to change the keybinds go in the code you should find some comments that shows how to change it. Its not very great considering the song starts once the first note is played so use a song that starts off with a beat or cut the music to start with a beat or smthing. Also, its doesn't sync super well with everything if you wanna remix you can but this isnt very good so you should use some other person's project.
the keys are set with the arrow keys so change it in the code sorry mobile players
