   • if you can’t find the BPM from google, then you can use BPM counters to manually measure the BPM ( by hitting the keyboard space key with the beat )

Video Summary:

1. don’t modify the audio file in anyway.
   • since the game uses a Youtube player to play music, your audio file must be identical to the youtube version without any changes.
2. To sync the level with the music, use a positive offset value in Chromapper ( as shown in the video above ). ( negative offset values should work, but they are not tested )
