@GrigoriFederov, I think the changes are made by the intensity of music, not how hard/fast/slow/easy it's the song. If the intensity of the music it's not so high, appear the white squares on the floor and hardly the ramps appear. The quantity of squares is kind of low. If the song reach a really high intensity then the ramps appears always, yellow/orange/red squares appears. The sides of the track start getting lighted and the screen moves like if a earthquake it's going on (sh***y english, sorry if you dont understand).
