The title of this mod suggests that you will have to make a lot of effort to change the simplest Expurgation song into a more complicated one. The backgrounds will also be updated while you will be changing the song. You will encounter the new menu with the cooler and more colourful sprites.
Control the gameplay with the common arrow keys on the PC’s keyboard or mobile, just like in any other mod to make all these changes. Try to sing and play all the notes correctly matching them in time and reach the end of the song to win. It is so simple that you can start right now. Have a lot of fun and enjoy every moment!
