Using the "Cosmic Key" file uploaded in sounds, record the melody of the song to open a dimensional portal that will allow you to travel. The more creative details you add to the song, background, etc., the better chance you have of using the "Cosmic Key" to opening the portal. Options: 1. You can use the sound already included and focus more on making sprites and/or backdrops to go with the song. 2. You can try to actually code the music. There are some sample notes already coded to the backdrop.
